We exhibit an attack against a signature scheme recently proposed by Gennaro, Halevi and Rabin [9]. The scheme's security is based on two assumptions namely the strong RSA ass...
Abstract. The Full Domain Hash (FDH) scheme is a RSA-based signature scheme in which the message is hashed onto the full domain of the RSA function. The FDH scheme is provably secu...
In 1999, two signature schemes based on the flexible RSA problem (a.k.a. strong RSA problem) were independently introduced: the Gennaro-Halevi-Rabin (GHR) signature scheme and the...
We discuss the following problem: Given an integer shared secretly among n players and a prime number e, how can the players efficiently compute a sharing of e-1 mod . The most in...
In this paper, we reinvestigate the security analysis of blind signature scheme over braid groups proposed by Verma in 2008. A blind signature scheme is a cryptographic primitive ...
