基于GF(qN)上秩距离码的校验矩阵的验证方案
AN IDENTIFICATION SCHEME BASED ON PARITY CHECK MATRIX OF RANK DISTANCE CODES OVER GF(qN)
-
摘要: J.Stern(1996)在公钥验证的一个新范例中基于GF(2)上纠错码的校验矩阵提出了一验证方案。该文基于GF(qN)(q为素数)上秩距离码的校验矩阵提出一新的验证方案,将J.Stern的方案中对秘密数据s的重量限制改为对s的秩的限制;证明了在随机预言模型中给出的协议是零知识交互证明,并显示出通过参数的适当选取,此方案比J.Stern的方案更安全。Abstract: An identification scheme based on parity check matrix of error-correcting codes over GF(2) was proposed in the paper A New Paradigm for Public Key Identification by J. Stern(1996), a new identification scheme based on parity check matrix of rank distance codes over GF(qN) (q is a prime) is proposed in this paper, the limitation on the weight of mysterious datum s is changed into the limitation on the rank of s. It is proved that the given protocol is a zero-knowledge interactive proof in the random oracle model, and it is shown that the scheme is more secure than the scheme of J. Stern when parameters are selected properly.
