Partially blind proxy re-signature scheme with proven security
摘要
Abstract
In order to solve the problem of anonymity and controllability of blind proxy re-signature, the concept of par-tially blind proxy re-signature was introduced by using the idea of partially blind signature. Furthermore, the security definition of partially blind proxy re-signature was also given. Based on the improved Shao scheme, a partially blind proxy re-signature scheme in the standard model was proposed. The proposed scheme allows proxy to add some public information negotiated by delegatee and proxy to re-signature. The scheme not only can achieve the transparent signature conversion from delegatee to proxy and protect privacy of message re-signed by proxy, but also prevented illegal use of re-signature. Analysis results show that the proposed scheme is correct, multi-use, partially blind and existentially un-forgeable. It is more suitable for e-government data exchange system, cross-domain authentication system and so on.关键词
