Information Security and Cryptology

Mathematics, Cryptology, Security

In this talk, I will review some of the work performed by the research community in cryptology and security since the invention of public key cryptography by Diffie and Hellman in 1976. This community has developped many challenging lines of research. I will only focus on some of these, and moreover I will adopt an extremely specific perspective: for each chosen example, I will try to trace the...

Strongly multiplicative linear secret sharing schemes (LSSS) have been a powerful tool for constructing secure multi-party computation protocols. However, it remains open whether or not there exist efficient constructions of strongly multiplicative LSSS from general LSSS. In this paper, we propose the new concept of a 3-multiplicative LSSS, and establish its relationship with strongly multiplic...

Contemporary Cryptology Provable Security for Public Key Schemes

Since the appearance of public-key cryptography in the Diffie-Hellman seminal paper, many schemes have been proposed, but many have been broken. Indeed, for a long time, the simple fact that a cryptographic algorithm had withstood cryptanalytic attacks for several years was considered as a kind of validation. But some schemes took a long time before being widely studied, and maybe thereafter be...
