Blind signature scheme based on GH-PKC
Xi Wang · Computer Engineering and Applications Journal · 2009
GH-PKC is a new public-key cryptosystem based on third-order LFSR sequences over GF(q),whose security is based on the difficulty of solving the discrete logarithm in GF(q3),but all computation are performed in GF(q).This paper proposes a ElGamal-like digital signature algorithm based on GH-PKC and then constructs a new blind signature scheme based on this,the security of which is equivalence to solving the discrete logarithm in GF(q3)while the datum transmitted is only as 1/3 as that of tranditional scheme.
