- Abstract
- There is proposed a method for designing the blind-signature schemes on the base of the hidden discrete logarithm problem that is set in the finite non-commutative associative algebras. The blind-signature protocol has been constructed using the 4-dimensional algebra as the algebraic carrier of the cryptoscheme. The algebra is defined over the ground finite field GF(p) and contains p2 different global right-sided units. The main properties of the algebra, which are connected with selection of the parameters of the protocol, are described.
