A Forward-Secure Public-Key Encryption Scheme
Cryptographic computations are often carried out on insecure devices for which the threat of key exposure represents a serious concern. Forward security allows one to mitigate the...

The Security of the FDH Variant of Chaum's Undeniable Signature Scheme
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...

Security Analysis of the Gennaro-Halevi-Rabin Signature Scheme
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...

Some RSA-Based Encryption Schemes with Tight Security Reduction
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...
