Abstract

Abstract:

Two blind signature schemes based on the discrete logarithm problem over inner automorphism group are proposed. The schemes satisfy blinding and one-more unforgery. These constructions can be viewed as non-communtative variants of blind signatures. Parameters and performance related issues are also addressed in detail.By comparison, the blind signatures are efficient in the running time and storage space.

Key words: blind signature, non-commutative group, discrete logarithm over inner automorphism group
