In this paper, we provide a threat model of possible privacy attacks on users utilizing the Bitcoin blockchain. To this end, we followed the LINDDUN GO methodology to identify threats and suggest possible mitigation.

In this work, we propose a (level-2) GGH13-encoding based zkSNARK which we show to be secure in the weak-multilinear map model of Miles-Sahai-Zhandry assuming a novel pseudo-random generator (PRG). We argue that the new PRG assumption is plausible based on the well-studied Newton's identity on power-sum polynomials, as well as an analysis of hardness of computing Grobner bases for these polynomials. The particular PRG is designed for efficient implementation of the zkSNARK.
Technically, we leverage the 2-linear instantiation of the GGH13 graded encoding scheme to provide us with an analogue of bilinear maps and adapt the Groth16 (Groth, Eurocrypt 2016) protocol, although with considerable technical advances in design and proof. The protocol is non-interactive in the CRS model.

AIT Austrian Institute of Technology; Vienna, Austria
The cryptography team is conducting research in the domain of public key cryptography, including secure communication, privacy-enhancing technologies, and long-term and post-quantum security. Our research covers the full spectrum from idea creation to the development of prototypes and demonstrators.
The team is seeking to grow, and is therefore offering a scientist position in cryptography.
Requirements:
- PhD (or equivalent) in computer science or a related field, with a specialization on (public-key) cryptology
- Profound knowledge and experience in (public key) cryptography, including, e.g.: federated computation, secure communication, long-term and post-quantum security, privacy-enhancing technologies, real world crypto, zero-knowledge proofs and zkSNARKs.
- Strong track record with publications at competitive academic conferences or journals
- Experience in the acquisition and execution of national and transnational research projects (e.g., Horizon 2020) is a plus
- Good knowledge of a programming language (e.g., C/C++, Rust, Python, Java) and software development is a plus
- Very good written and oral English skills; knowledge of German is not a requirement but willingness to learn German is expected
The minimum gross annual salary on a full-time basis (38,5 h / week) according to the collective agreement is EUR 61.614,--. The actual salary will be determined individually, based on your qualifications and experience. In addition, we offer company benefits, flexible working conditions, individual training and career opportunities.
All applications (including cover letter, full CV, at least 2 references) need to be submitted using the following link: https://jobs.ait.ac.at/Job/218885
