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教字签名算法,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.

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 pro-poses 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.
