Cryptoschemes Based on New Signature Formation Mechanism
Alexander Andreevich Moldovyan, Dmitriy Nikolaevich Moldovyan, L.V. Gortinskaya · 2006
Several variants of new digital signature schemes (DSS) based on the discrete logarithm and factorization problems have been proposed. Considered DSS are characterized in that a novel mechanism of the signature generation is used, in which two parameters of the (k;S) or (R;S) signature are defined after solving a system of two congruences. In the case of composite modulus additional restrictions conditions have been introduced for selection of the public key.
