On the Rabin signature
Michele Elia, Davide Schipani
Some Rabin signature schemes may be exposed to forgery; several variants are here described to counter this vulnerability. Blind Rabin signatures are also discussed.
The Rabin cryptosystem revisited
Michele Elia, Matteo Piva, Davide Schipani
The Rabin public-key cryptosystem is revisited with a focus on the problem of identifying the encrypted message unambiguously for any pair of primes. In particular, a deterministic…
Enhanced public key security for the McEliece cryptosystem
Marco Baldi, Marco Bianchi, Franco Chiaraluce +2
This paper studies a variant of the McEliece cryptosystem able to ensure that the code used as the public key is no longer permutation-equivalent to the secret code. This increases…
Additive decompositions induced by multiplicative characters over finite fields
Davide Schipani, Michele Elia
In 1952, Perron showed that quadratic residues in a field of prime order satisfy certain ad- ditive properties. This result has been generalized in different directions, and our co…
On fuzzy syndrome hashing with LDPC coding
Marco Baldi, Marco Bianchi, Franco Chiaraluce +2
The last decades have seen a growing interest in hash functions that allow some sort of tolerance, e.g. for the purpose of biometric authentication. Among these, the syndrome fuzzy…
Managing key multicasting through orthogonal systems
Jose' Antonio Alvarez-Bermejo, Juan Antonio Lopez-Ramos, Joachim Rosenthal +1
In this paper we propose a new protocol to manage multicast key distribution. The protocol is based on the use of orthogonal systems in vector spaces. The main advantage in compari…
