A DSA-like digital signature protocol
Leila Zahhafi, Omar Khadir
In this paper we propose a new digital signature protocol inspired by the DSA algorithm. The security and the complexity are analyzed. Our method constitutes an alternative if the…
Algorithm for factoring some RSA and Rabin moduli
Omar Khadir
In this paper we present a new efficient algorithm for factoring the RSA and the Rabin moduli in the particular case when the difference between their two prime factors is bounded.…
New variant of ElGamal signature scheme
Omar Khadir
In this paper, a new variant of ElGamal signature scheme is presented and its security analyzed. We also give, for its theoretical interest, a general form of the signature equatio…
Conditions on the generator for forging ElGamal signature
Omar Khadir
This paper describes new conditions on parameters selection that lead to an efficient algorithm for forging ElGamal digital signature. Our work is inspired by Bleichenbacher's idea…
New digital signature protocol based on elliptic curves
Ounasser Abid, Jaouad Ettanfouhi, Omar Khadir
In this work, a new digital signature based on elliptic curves is presented. We established its efficiency and security. The method, derived from a variant of ElGamal signature sch…
