Abstract. The CBC-MAC or cipher block chaining message authentication code, is a well-known method to generate message authentication codes. Unfortunately, it is not forgery-secure...
The Pintsov-Vanstone signature scheme with partial message recovery (PVSSR) is a variant of the Schnorr and Nyberg-Rueppel signature schemes. It produces very short signatures on ...
Abstract. For the homomorphic Paillier cryptosystem we construct a protocol for secure modulo reduction, that on input of an encryption x with x of bit length x and a public ‘mod...
Group signature schemes are cryptographic systems that provide revocable anonymity for signers. We propose a group signature scheme with constant-size public key and signature leng...
Abstract. The problem of perfectly secure message transmission concerns two synchronized non-faulty processors sender (S) and receiver (R) that are connected by a synchronous netwo...
