On the one hand, the web needs to be secured from malicious activities such as bots or DoS attacks; on the other hand, such needs ideally should not justify services tracking people's activities on the web. Anonymous tokens provide a nice tradeoff between allowing an issuer to ensure that a user has been vetted and protecting the users' privacy. However, in some cases, whether or not a token is issued reveals a lot of information to an adversary about the strategies used to distinguish honest users from bots or attackers.
In this work, we focus on designing an anonymous token protocol between a client and an issuer (also a verifier) that enables the issuer to support its fraud detection mechanisms while preserving users' privacy. This is done by allowing the issuer to embed a hidden (from the client) metadata bit into the tokens. We first study an existing protocol from CRYPTO 2020 which is an extension of Privacy Pass from PoPETs 2018; that protocol aimed to provide support for a hidden metadata bit, but provided a somewhat restricted security notion. We demonstrate a new attack, showing that this is a weakness of the protocol, not just the definition. In particular, the metadata bit hiding is weak in the setting where the attacker can redeem some tokens and get feedback on what bit is extracted.
We then revisit the formalism of anonymous tokens with private metadata bit, consider the more natural notion, and design a scheme which achieves it. In order to design this new secure protocol, we base our construction on algebraic MACs instead of PRFs. Our security definitions capture a realistic threat model where adversaries could, through direct feedback or side channels, learn the embedded bit when the token is redeemed. Finally, we compare our protocol with one of the CRYPTO 2020 protocols which we obtain 20\% more efficient implementation.

Private comparison schemes constructed on homomorphic encryption offer the noninteractive, output expressive and parallelizable features, and have advantages in communication bandwidth and performance. In this paper, we propose cuXCMP, which allows negative and float inputs, offers fully output expressive feature, and is more extensible and practical compared to XCMP (AsiaCCS 2018). Meanwhile, we introduce several memory-centric optimizations of the constant term extraction kernel tailored for CUDA-enabled GPUs. Firstly, we fully utilize the shared memory and present compact GPU implementations of NTT and INTT using a single block; Secondly, we fuse multiple kernels into one AKS kernel, which conducts the automorphism and key switching operation, and reduce the grid dimension for better resource usage, data access rate and synchronization. Thirdly, we precisely measure the IO latency and choose an appropriate number of CUDA streams to enable concurrent execution of independent operations, yielding a constant term extraction kernel with perfect latency hide, i.e., CTX. Combining these approaches, we boost the overall execution time to optimum level and the speedup ratio increases with the comparison scales. For one comparison, we speedup the AKS by 23.71×, CTX by 15.58×, and scheme by 1.83× (resp., 18.29×, 11.75×, and 1.42×) compared to C (resp., AVX512) baselines, respectively. For 32 comparisons, our CTX and scheme implementations outperform the C (resp., AVX512) baselines by 112.00× and 1.99× (resp., 81.53× and 1.51×).

Public verification of quantum money has been one of the central objects in quantum cryptography ever since Wiesner's pioneering idea of using quantum mechanics to construct banknotes against counterfeiting. So far, we do not know any publicly-verifiable quantum money scheme that is provably secure from standard assumptions.
In this work, we provide both negative and positive results for publicly verifiable quantum money.
**In the first part, we give a general theorem, showing that a certain natural class of quantum money schemes from lattices cannot be secure. We use this theorem to break the recent quantum money scheme of Khesin, Lu, and Shor. **In the second part, we propose a framework for building quantum money and quantum lightning we call invariant money which abstracts some of the ideas of quantum money from knots by Farhi et al.(ITCS'12). In addition to formalizing this framework, we provide concrete hard computational problems loosely inspired by classical knowledge-of-exponent assumptions, whose hardness would imply the security of quantum lightning, a strengthening of quantum money where not even the bank can duplicate banknotes.
**We discuss potential instantiations of our framework, including an oracle construction using cryptographic group actions and instantiations from rerandomizable functional encryption, isogenies over elliptic curves, and knots.

For avoding the attacks from quantum computing (QC), this study applies the post-quantum cryptography (PQC) methods without hidden subgroups to the security of vehicular communications. Due the mainstream technologies of PQC methods (i.e. lattice-based cryptography methods), the standard digital signature methods including Dilithium and Falcon have been discussed and compared. This study uses a queueing model to analyze the performance of these standard digital signature methods for selection decision-making.

Zero-knowledge Succinct Non-interactive ARguments of Knowledge (zkSNARKs) are becoming an increasingly fundamental tool in many real-world applications where the proof compactness is of the utmost importance, including blockchains. A proof of security for SNARKs in the Universal Composability (UC) framework (Canetti, FOCS'01) would rule out devastating malleability attacks. To retain security of SNARKs in the UC model, one must show their simulation-extractability such that the knowledge extractor is both black-box and straight-line, which would imply that proofs generated by honest provers are non-malleable. However, existing simulation-extractability results on SNARKs either lack some of these properties, or alternatively have to sacrifice witness succinctness to prove UC security.
In this paper, we provide a compiler lifting any simulation-extractable NIZKAoK into a UC-secure one in the global random oracle model, importantly, while preserving the same level of witness succinctness. Combining this with existing zkSNARKs, we achieve, to the best of our knowledge, the first zkSNARKs simultaneously achieving UC-security and constant sized proofs.

RAGHAV is a 64-bit block cipher proposed by Bansod in 2021. It supports 80-, and 128-bit secret keys. The designer evaluated its security against typical attack, such as differential cryptanalysis, linear cryptanalysis, and so on. On the other hand, it has not been reported the security of RAGHAV against higher order differential attack, which is one of the algebraic attacks. In this paper, we applied higher order differential cryptanalysis to RAGHAV. As a results, we found a new full-round higher order characteristic of RAGHAV using 1-st order differential. Exploiting this characteristic, we also show that the full-round of RAGHAV is attackable by distinguishing attack with 2 chosen plaintexts.

Sharing a secret efficiently amongst a group of participants is not easy since there is always an adversary / eavesdropper trying to retrieve the secret. In secret sharing schemes, every participant is given a unique share. When the desired group of participants come together and provide their shares, the secret is obtained. For other combinations of shares, a garbage value is returned. A threshold secret sharing scheme was proposed by Shamir and Blakeley independently. In this (n,t) threshold secret sharing scheme, the secret can be obtained when at least $t$ out of $n$ participants contribute their shares. This paper proposes a novel algorithm to reveal the secret only to the subsets of participants belonging to the access structure. This scheme implements totally generalized ideal secret sharing. Unlike threshold secret sharing schemes, this scheme reveals the secret only to the authorized sets of participants, not any arbitrary set of users with cardinality more than or equal to $t$. Since any access structure can be realized with this scheme, this scheme can be exploited to implement various access priorities and access control mechanisms. A major advantage of this scheme over the existing ones is that the shares being distributed to the participants is totally independent of the secret being shared. Hence, no restrictions are imposed on the scheme and it finds a wider use in real world applications.

The recent advent of cloud computing and IoT has made it imperative to store huge amount of data in the cloud servers. Enormous amount of data is also stored in the servers of big organizations. In organizations, it is not desirable for every member to have equal privileges to access the stored data. Threshold secret sharing schemes are widely used for implementing such access control mechanisms. The access privileges of the members also vary from one data packet to another. While implementing such dynamic access structures using threshold secret sharing schemes, the key management becomes too complex to be implemented in real time. Furthermore, the storage of the users’ access privileges requires exponential space (O($2^n$)) and its implementation requires exponential time. In this paper, the algorithms proposed to tackle the problems of
priority based access control and authentication require a space complexity of O($n^2$) and a time complexity of O($n$), where n is the number of users. In the practical scenario, such space can easily be provided on the servers and the algorithms can run smoothly in real time.

Off-chain payment channels were introduced as one of the solutions to the blockchain scalability problem. The channels shape a network, where parties have to lock funds for their creation. A channel is expected to route a limited number of transactions before it becomes unbalanced, when all of the funds are devoted to one of the parties. Since an on-chain transaction is often necessary to establish, rebalance, or close a channel, the off-chain network is bounded to the throughput of the blockchain.
In this paper, we propose a mathematical model to formulate limitation on the throughput of an off-chain payment network. As a case study, we show the limitation of the Lightning Network, in comparison with popular banking systems. Our results show that theoretically, the throughput of the Lightning Network can reach the order of 10000 transactions per second, close to the average throughput of centralized banking systems.

Classic McEliece is a code based encryption scheme and candidate of the NIST post quantum contest. Implementing Classic McEliece on smart card chips is a challenge, because those chips have only a very limited amount of RAM. Decryption is not an issue because the cryptogram size is short and the decryption algorithm can be implemented using very few RAM. However key generation is a concern, because a large binary matrix must be inverted.
In this paper, we show how key generation can be done on smart card chips with very little RAM resources. This is accomplished by modifying the key generation algorithm and splitting it in a security critical part and a non security critical part. The security critical part can be implemented on the smart card controller. The non critical part contains the matrix inversion and will be done on a connected host.

Zero-knowledge proofs allow a prover to convince a verifier of a statement without revealing anything besides its validity. A major bottleneck in scaling sub-linear zero-knowledge proofs is the high space requirement of the prover, even for NP relations that can be verified in a small space.
In this work, we ask whether there exist complexity-preserving (i.e. overhead w.r.t time and space are minimal) succinct zero-knowledge arguments of knowledge with minimal assumptions while making only black-box access to the underlying primitives. We design the first such zero-knowledge system with sublinear communication complexity (when the underlying $\textsf{NP}$ relation uses non-trivial space) and provide evidence why existing techniques are unlikely to improve the communication complexity in this setting. Namely, for every NP relation that can be verified in time T and space S by a RAM program, we construct a public-coin zero-knowledge argument system that is black-box based on collision-resistant hash-functions (CRH) where the prover runs in time $\widetilde{O}(T)$ and space $\widetilde{O}(S)$, the verifier runs in time $\widetilde{O}(T/S+S)$ and space $\widetilde{O}(1)$ and the communication is $\widetilde{O}(T/S)$, where $\widetilde{O}()$ ignores polynomial factors in $\log T$ and $\kappa$ is the security parameter. As our construction is public-coin, we can apply the Fiat-Shamir heuristic to make it non-interactive with sample communication/computation complexities.
Furthermore, we give evidence that reducing the proof length below $\widetilde{O}(T/S)$ will be hard using existing symmetric-key based techniques by arguing the space-complexity of constant-distance error correcting codes.

BLS signatures have fast aggregated signature verification but slow individual signature verification. We propose a three part optimisation that dramatically reduces CPU time in large distributed system using BLS signatures: First, public keys should be given on both source groups $\mathbb{G}_1$ and $\mathbb{G}_2$, with a proof-of-possession check for correctness. Second, aggregated BLS signatures should carry their particular aggregate public key in $\mathbb{G}_2$, so that verifiers can do both hash-to-curve and aggregate public key checks in $\mathbb{G}_1$. Third, individual non-aggregated BLS signatures should carry short Chaum-Pedersen DLEQ proofs of correctness, so that verifying individual signatures no longer requires pairings, which makes their verification much faster. We prove security for these optimisations. The proposed scheme is implemented and benchmarked to compare with classic BLS scheme.

QC-MDPC (quasi cyclic moderate density parity check) code-based McEliece cryptosystems are considered to be one of the candidates for post-quantum cryptography. Decreasing DER (decoding error rate) is one of important factor for their security, since recent attacks to these cryptosystems effectively use DER information.
In this paper, we pursue the possibility of optimization-base decoding, concretely we examine ADMM (alternating direction method of multipliers), a recent developing method in optimization theory. Further, RSPA (reproducing sum-product algorithm), which efficiently reuse outputs of SPA (sum-product algorithm) is proposed for the reduction of execution time in decoding. By numerical simulations, we show that the proposing scheme shows considerable decrement in DER compared to the conventional decoding methods such as BF (bit-flipping algorithm) variants or SPA.

The desirable encryption scheme possesses high PRF security, high efficiency, and the ability to produce variable-length outputs. Since designing dedicated secure PRFs is difficult, a series of works was devoted to building optimally secure PRFs from the sum of independent permutations (SoP), Encrypted Davies-Meyer (EDM), its Dual (EDMD), and the Summation-Truncation Hybrid (STH) for variable output lengths, which can be easily instantiated from existing permutations. For increased efficiency, reducing the number of operations in established primitives has been gaining traction: Mennink and Neves pruned EDMD to FastPRF, and Andreeva et al. introduced ForkCiphers, which take an n-bit input, process it through a reduced-round permutation, fork it into two states, and feed each of them into another reduced-round permutation to produce a 2n-bit output. The constructions above can be used in secure variable-length modes or generalizations such as MultiForkCiphers.
In this paper, we suggest a framework of those constructions in terms of the three desiderata: we span the spectrum of (1) output length vs. PRF security, (2) full vs. round-reduced primitives, and (3) fixed- vs. variable-length outputs. From this point of view, we identify remaining gaps in the spectrum and fill them with the proposal of several highly secure and efficient fixed- and variable-output-length PRFs.
We fork SoP and STH to ForkPRF and ForkSTH, extend STH to the variable-output-length construction STHCENC, which bridges the gap between CTR mode and CENC,and propose ForkCENC, ForkSTHCENC, ForkEDMD, as well as ForkEDM-CTR as the variable-output-length and round-reduced versions of CENC, STH, FastPRF, and FastPRF's dual, respectively.
Using recent results on Patarin's general Mirror Theory, we have proven that almost all our proposed PRFs are optimally secure under the assumption that the permutations are pairwise independent and random and STH achieves the optimal security depending on the output length. Our constructions can be highly efficient in practice. We propose efficient instantiations from round-reduced AES and back it with the cryptanalysis lessons learned from existing earlier analysis of AES-based primitives.

We design and implement a simple zero-knowledge argument protocol for $\mathsf{NP}$ whose communication complexity is proportional to the square-root of the verification circuit size. The protocol can be based on any collision-resistant hash function. Alternatively, it can be made non-interactive in the random oracle model, yielding concretely efficient zk-SNARKs that do not require a trusted setup or public-key cryptography. Our protocol is obtained by applying an optimized version of the general transformation of Ishai et al. (STOC 2007) to a variant of the protocol for secure multiparty computation of Damg$\mathring{a}$rd and Ishai (CRYPTO 2006). It can be viewed as a simple zero-knowledge interactive PCP based on ``interleaved'' Reed-Solomon codes.
This paper is an extended version of the paper published in CCS 2017 and features a tighter analysis, better implementation along with formal proofs. For large verification circuits, the Ligero prover remains competitive against subsequent works with respect to the prover’s running time, where our efficiency advantages become even bigger in an amortized setting, where several instances need to be proven simultaneously.
Our protocol is attractive not only for very large verification circuits but also for moderately large circuits that arise in applications. For instance, for verifying a SHA-256 preimage with $2^{-40}$ soundness error, the communication complexity is roughly 35KB.
The communication complexity of our protocol is independent of the circuit structure and depends only on the number of gates. For $2^{-40}$ soundness error, the communication becomes smaller than the circuit size for circuits containing roughly 3 million gates or more. With our refined analysis the Ligero system's proof lengths and prover's running times are better than subsequent post-quantum ZK-SNARKs for small to moderately large circuits.

A Password-Authenticated Key Exchange (PAKE) protocol allows two parties to agree upon a cryptographic key, when the only information shared in advance is a low-entropy password. The standard security notion for PAKE (Canetti et al., Eurocrypt 2005) is in the Universally Composable (UC) framework. We show that unlike most UC security notions, UC PAKE does not imply correctness. While Canetti et al. seems to have implicitly noticed this issue, it has yet to be explicitly identified by the PAKE literature. We present a comprehensive study of correctness in UC PAKE:
1. We show that TrivialPAKE, a no-message protocol that does not satisfy correctness, is a UC PAKE;
2. We propose nine approaches to guaranteeing correctness in the UC security notion of PAKE, and show that seven of them are equivalent, whereas the other two are unachievable;
3. We prove that a direct solution, namely changing the UC PAKE functionality to incorporate correctness, is impossible;
4. Finally, we show how to naturally incorporate correctness by changing the model — we view PAKE as a three-party protocol, with the man-in-the-middle adversary as the third party.
In this way, we hope to shed some light on the very nature of UC-security in the man-in-the-middle setting.

Accountability is a well-established and widely used security concept that allows for obtaining undeniable cryptographic proof of misbehavior, thereby incentivizing honest behavior. There already exist several general purpose accountability frameworks for formal game-based security analyses. Unfortunately, such game-based frameworks do not support modular security analyses, which is an important tool to handle the complexity of
modern protocols.
Universal composability (UC) models provide native support for modular analyses, including re-use and composition of security results. So far, accountability has mainly been modeled and analyzed in UC models for the special case of MPC protocols, with a general purpose accountability framework for UC still missing. That is, a framework that among others supports arbitrary protocols, a wide range of accountability properties, handling and mixing of accountable and non-accountable security properties, and modular analysis of accountable protocols.
To close this gap, we propose AUC, the first general purpose accountability framework for UC models, which supports all of the above, based on several new concepts. We exemplify AUC in three case studies not covered by existing works. In particular, AUC unifies existing UC accountability approaches within a single framework.

Fair exchange (also referred to as atomic swap) is a fundamental operation in any cryptocurrency, that allows users to atomically exchange coins. While a large body of work has been devoted to this problem, most solutions lack on-chain privacy. Thus, coins retain a public transaction history which is known to degrade the fungibility of a currency. This has led to a flourishing line of related research on fair exchange with privacy guarantees. Existing protocols either rely on heavy scripting (which also degrades fungibility), do not support atomic swaps across a wide range currencies, or come with incomplete security proofs.
To overcome these limitations, we introduce Sweep-UC (Read as Sweep Ur Coins), the first fair exchange protocol that simultaneously is efficient, minimizes scripting, and is compatible with a wide range of currencies (more than the state of the art). We build Sweep-UC from modular subprotocols and give a rigorous security analysis in the UC-framework. Many of our tools and security definitions can be used in standalone fashion and may serve as useful components for future constructions of fair exchange.

ARIA is a block cipher proposed by Kwon et al. at ICISC 2003, and it is widely used as the national standard block cipher in the Republic of Korea. In this study, we identify some flaws in the quantum rebound attack on 7-round ARIA-DM proposed by Dou et al., and we reveal that the limit of this attack is up to 5-round. Our revised attack applies not only to ARIA-DM but also to ARIA-MMO and ARIA-MP among the PGV models, and it is valid for all key lengths of ARIA. Moreover, we present dedicated quantum rebound attacks on 7-round ARIA-Hirose and ARIA-MJH for the first time. These attacks are only valid for the 256-bit key length of ARIA because they are constructed using the degrees of freedom in the key schedule. All our attacks are faster than the generic quantum attack in the cost metric of time–space tradeoff.
