Abstract

Abstract: 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.

Key words: 3rd-order linear feedback shift register, characteristic sequence, irreducible polynomial, blind signature

摘要： GH-PKC是一种新的基于GF（q）上三级线性反馈移位寄存器序列的公钥密码体制。其安全性基于有限域GF（q3）上的离散对数困难问题，但运算却在有限域GF（q）中进行。文中给出了一种新的基于GH-PKC的类ELGamal数字签名算法，并在此基础上构建了基于GH-PKC的盲签名方案，其安全性等价于解GF（q3）上离散对数困难问题，但是传输的数据量只有传统方案的1/3。

关键词: 3级线性反馈移位寄存器, 特征序列, 不可约多项式, 盲签名
