- Abstract
- A novel blind digital signature protocol is introduced, which is based on a hidden logarithm problem set in a finite 4-dimensional commutative algebra with associative multiplication operation. The used algebra is defined over the ground finite field GF (p). Multiplicative group of the algebra possesses 4-dimensional cyclicity. The public key is generated in the form of a triple of vectors that are generators of three different cyclic subgroups. Three blinding factors are used in the developed protocol to insure the anonymity property of the protocol.
