Proxy blind signature, which combines the properties of both proxy signature and blind signature, is useful in many applications. Based on ECLDP, Wang et al. recently proposed a proxy blind signature scheme. In this paper, we present a security analysis on Wang's scheme and prove it does not possess the strong nonrepudiation, strong unforgeability and unlink- ability properties by three efficient...
Privacy-preserving cooperative linear system of equations problem is an important scientific computation and widely used in many areas such as banking, manufacturing, and telecommunications. In this paper, we present a new privacy- preserving cooperative linear system of equations protocol under the semi-honest mode, which is more efficient as compared with existing schemes. The security of the newly...
Proxy blind signature, which combines the properties of both proxy signature and blind signature, is useful in many applications. In this paper, we present a new proxy blind signature scheme based on discrete logarithm problem, which satisfies the secure properties of both the blind signature scheme and the proxy signature scheme. As compared with existing typical schemes, our scheme is more efficient.
