Identity-based proxy re-signature over ideal lattice
摘要
Abstract
As an important tool of key management, the proxy re-signature scheme can not only simplify the secret key management and certificate management, but also can be used to provide certificate path and so on. Currently, for the diffi-culty of integer factorizating and logarithm discretization and the insecurity of proxy re-signature schemes in the quantum environments, a proxy re-signature scheme that can resist the attack of quantum has been presented in the literature. The first identity-based proxy re-signature scheme over ideal lattice is constructed in this paper, by using ideal lattice and based on the difficulty of the Small Integer Solution(SIS)problem. Compared with other proxy re-signature scheme that has the same properties, this has a shorter signature, and public key, and the advantage of decreasing the computational complexity.关键词
