基于多变量公钥密码体制的代理重签名方案
Proxy Re-signature Scheme Based on Multivariate Public Key Cryptography
摘要
Abstract
Almost proxy re-signature schemes are hardness of big integer factoring problem and Discrete Logarithm(DL) problem. But the quantum computer can solve this question in polynomial time, which may cause potential security risks to the schemes. This paper uses the characteristics that multivariate public key cryptography can resist quantum computer attack, to design a new proxy re-signature scheme. Theoretical analysis shows that the scheme fits internal and external security, and it is efficient.关键词
