In this paper we propose a solution to enable an accurate terminal revocation in the Extended Access Control (EAC). Chaabouni and Vaudenay in [CV09] pointed out the need for an accurate revocation procedure, but failed to provide a complete solution descri ...
Privacy has recently gained an importance beyond the field of cryptography. In that regard, the main goal behind this thesis is to enhance privacy protection. All of the necessary mathematical and cryptographic preliminaries are introduced at the start of ...
In a range proof, the prover convinces the verifier in zero-knowledge that he has encrypted or committed to a value a ∈ [0,H] where H is a public constant. Most of the previous non-interactive range proofs have been proven secure in the random oracle model ...
Many online transactions require the sharing of identity information, even though this sharing poses substantial trust challenges, both for the sender and the receiver. For this reason, Internet must provide channels to ensure a secure, reliable, private, ...

A method for providing efficient management of certificate revocation may comprise storing a list of identifiers of digital certificates including a revocation list defining a list of revoked certificates in an accumulator, storing a witness value in assoc ...
We show how to express an arbitrary integer interval I=[0,H] as a sumset I=∑i=1ℓGi∗[0,u−1]+[0,H′] of smaller integer intervals for some small values ℓ, u, and H′<u−1, where b∗A={ba:a∈A} and $A + B = ...
Machine Readable travel documents have been rapidly put in place since 2004. The initial standard was made by the ICAO and it has been quickly followed by the Extended Access Control (EAC). In this presentation, we discuss about the evolution of these stan ...
A method and apparatus for proving and a method and apparatus for verifying that a secret value is a member of a predetermined set of values. The proving mechanism receives a set of signatures which has respective values in the predetermined set signed usi ...
