The notion of verifiable database (VDB) enables a resource-constrained client to securely
outsource a very large database to an untrusted server so that it could later retrieve a …

In typical applications of homomorphic encryption, the first step consists for Alice of
encrypting some plaintext m under Bob's public key pk pk and of sending the ciphertext c …

Recently many pairing-based cryptographic protocols have been designed with a wide
variety of new novel applications including the ones in the emerging technologies like cloud …

Several fault attacks against pairing-based cryptography have been described theoretically
in recent years. Interestingly, none of these has been practically evaluated. We accomplish …

In this paper, we revisit the recent small characteristic discrete logarithm algorithms. We
show that a simplified description of the algorithm, together with some additional ideas …

Abstract We propose a Dynamic Universal Accumulator in the Accumulator Manager setting
for bilinear groups which extends Nguyen's positive accumulator and Au et al. and Damgård …

The notion of verifiable database with updates (VDB) enables a resource-limited client to
securely outsource a very large database to an untrusted server, and the client could later …

Due to its use in cryptographic protocols such as the Diffie–Hellman key exchange, the
discrete logarithm problem attracted a considerable amount of attention in the past 40 years …

This paper describes the first constructions of identity-based broadcast encryption (IBBE)
using Type-3 pairings, which can be proved secure against adaptive-identity attacks based …

Since 2013 there have been several developments in algorithms for computing discrete
logarithms in small-characteristic finite fields, culminating in a quasi-polynomial algorithm. In …
