The strongest standard security notion for digital signature schemes is unforgeability under chosen message attacks. In practice, however, this notion can be insufficient due to â€...

Abstract. In this paper a novel theoretical security analysis will be presented for data hiding methods with side-information, based on Costa’s dirty paper scheme. We quantify th...
In 2004, Yoon et al. proposed a user authentication scheme based on generalized ElGamal signature scheme using smart cards. In their scheme, the previous session keys will be comp...
Abstract. We would like to quantify the assurance contained in an authentication secret. For instance, how much assurance does a customer convey to a bank by revealing that his Per...
The inherent key escrow problem is one of the main reasons for the slow adoption of identity-based cryptography. The existing solution for mitigating the key escrow problem is by a...
