On the Privacy Enhancement of In-Transit Health Data Inspection: A Preliminary Study
A new healthcare paradigm has emerged lately placing patients at the center of the healthcare scenario, providing more control over their data. Allowing patients to access data from outside healthcare organiza...

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...

Comparison of Mechanisms
In this chapter we compare Privacy-ABC schemes based on the security, functionality and efficiency they offer. The aim of this is to help researchers and application developers choose an schemes and parameters...

On the Security of Distributed Multiprime RSA
Threshold RSA encryption and signing is a very useful tool to increase the security of the secret keys used. Key generation is, however, either done in a non-threshold way, or computationally inefficient proto...

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...

On the Theory and Practice of Personal Digital Signatures
We take a step towards a more realistic modeling of personal digital signatures, where a human user, his mobile equipment, his PC and a server are all considered as independent players in the protocol, and whe...
