ePrint ReportCompared to conventional auditor-based approaches, DAPOL provides a privacy preserving mechanism for users to validate their vote or amount inclusion in the reported total of liabilities/obligations and complements the traditional validation performed by the auditors by adding extra privacy and fairness guarantees. The recommended approach combines previously known cryptographic techniques to provide a layered solution with predefined levels of privacy in the form of gadgets. The backbone of this proposal is based on the enhanced Maxwell Merkle-tree construction and is extended using zero knowledge proofs, sparse trees, balance splitting tricks, efficient padding, verifiable random functions, deterministic key derivation functions and the range proof techniques from Provisions and ZeroLedge solvency protocols, respectively.

ePrint ReportWe present a scalable solution for implementing this functionality on a public proof-of-stake blockchain, in the presence of a mobile adversary controlling a small minority of the stake, using proactive secret sharing techniques. The main challenge is that, on the one hand, scalability requires that we use small committees to represent the entire stake, but, on the other hand, a mobile adversary may be able to corrupt the entire committee if it is small. For this reason, prior proactive secret sharing solutions are either non-scalable or insecure in our setting.
We solve this issue using "player replaceability", where the committee is anonymous until after it performs its actions, as in the Algorand blockchain. (Algorand uses player replaceability to defend against DDoS attacks.) Our main technical contribution is a system that allows sharing and re-sharing of secrets among the members of small dynamic committees, without knowing who they are until after they perform their actions. Our solution handles a fully mobile adversary corrupting less than 25\% of the stake at any time, and is scalable in terms of both the number of parties on the blockchain and the number of time intervals.

XLIM, University of Limoges (France)
Job PostingThis Ph.D. thesis is offered as part of the ANR-funded 4-year research project MobiS5. The goal of MobiS5 is to provide a cryptographic toolbox for the emerging 5G technologies. More information can be found at: https://mobis5.limos.fr/index.html.
This 3-year Ph.D. thesis will focus on the two following aspects of 5G security:
- 5G Core Network security
- Delegation in the context of 5G networks

CentraleSupélec - INSA, Institute of Electronics & Telecommunications of Rennes (IETR), France
Job PostingThis PhD will study the impact that close-by digital-analog-RF domains in mixed-signal reconfigurable platforms may have on new system vulnerabilities. The thesis will focus on studying data leakage mechanisms in RFSoCs to analyze and understand potential new threats linked to their reconfigurable and mixed-signal nature as a first step to find adequate countermeasures.
The candidate must hold a Master degree in Computer/Electrical Engineering, Embedded Systems, Microelectronics, or Computer Science and demonstrate strong background in several of the following topics: Digital design with HDLs; Reconfigurable computing, FPGAs; Hardware security; Embedded systems architectures; Microelectronics/VLSI Design. Knowledge on cryptographic algorithms implementations, C/C++/Python programming and Linux/Git as development environment are highly valuable.
You will receive a 3 year PhD contract and social security coverage, subsidized meals, partial reimbursement of public transport costs, support with accommodation at the campus and access to vocational training and social, cultural and sports events and activities. Send your CV, Bachelor/Master transcripts, a motivational text and reference letter before May 10, 2020.
