A generalization of Paillier's public-key system with applications to electronic voting
We propose a generalization of Paillier's probabilistic public key system, in which the expansion factor is reduced and which allows to adjust the block length of the scheme e...

Validity Models of Electronic Signatures and Their Enforcement in Practice
Abstract. An electronic signature is considered to be valid, if the signature is mathematically correct and if the signer's public key is classified as authentic. While the fi...

CyclicRainbow - A Multivariate Signature Scheme with a Partially Cyclic Public Key
Multivariate Cryptography is one of the alternatives to guarantee the security of communication in the post-quantum world. One major drawback of such schemes is the huge size of th...

On the Insecurity of Parallel Repetition for Leakage Resilience
A fundamental question in leakage-resilient cryptography is: can leakage resilience always be amplified by parallel repetition? It is natural to expect that if we have a leakage-r...

A proposal for collaborative internet-scale trust infrastructures deployment: the public key system (PKS)
Public Key technology is about multiple parties across different domains making assertions that can be chained together to make trust judgments. Today, the need for more interoper...

A formalisation and evaluation of certificate policies
Certificate policies play a central role in public key infrastructures, since they are the basis for the evaluation of trust in binding between a key and a subject in a public key...

Discrete Logarithms: The Past and the Future
The first practical public key cryptosystem to be published, the Diffie-Hellman key exchange algorithm, was based on the assumption that discrete logarithms are hard to compute. T...
