An Untraceable Blind Signature Scheme

摘要

In this paper, the authors intend to propose a new untraceable blind signature scheme based on the RSA cryp-tosystem. This paper applies the Extended Euclidean algorithm to our blind signature scheme. Compared with other blind signature schemes, our proposed scheme can meet the all requirements of a blind signature scheme. The security of the proposed scheme, as did that of the RSA cryptosystem, depends on the difficulty of solving the factoring problem.
