Efficient RSA Key Generation and Threshold Paillier in the Two-Party Setting
The problem of generating an RSA composite in a distributed manner without leaking its factorization is particularly challenging and useful in many cryptographic protocols. Our first contribution is the first ...

Formal Treatment of Privacy-Enhancing Credential Systems
Privacy-enhancing attribute-based credentials (PABCs) are the core ingredients to privacy-friendly authentication systems. They allow users to obtain credentials on attributes and prove possession of these creden...

Efficient Threshold Zero-Knowledge with Applications to User-Centric Protocols
In this paper, we investigate on threshold proofs, a framework for distributing the prover’s side of interactive proofs of knowledge over multiple parties. Interactive proofs of knowledge (PoK) are widely used pr...

Efficient, Robust and Constant-Round Distributed RSA Key Generation
We present the first protocol for distributed RSA key generation which is constant round, secure against malicious adversaries and has a negligibly small bound on the error probability, even using only one ite...
