In this paper, we first introduce a new kind of adversarial goal called forge-and-impersonate in undeniable signature schemes. Note that forgeability does not necessarily imply im...

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...

In this paper, we study some RSA-based semantically secure encryption schemes (IND-CPA) in the standard model. We first derive the exactly tight one-wayness of Rabin-Paillier encr...
