基于多变量公钥密码的代理环签名方案

多变量公钥密码是后量子密码的可选方案之一,受到了广泛的关注。由于已有的代理环签名方案大多基于大整数分解和离散对数等难题设计,都不能抵抗量子计算机的攻击,因此基于多变量公钥密码设计出了一个新的代理环签名方案,该方案基于MQ问题及IP问题设计,不仅满足代理环签名的各项性能要求,还具有抗量子计算特性,且计算简单,效率更高。

Multivariate Public Key Cryptography-Based Proxy Ring Signature Scheme

The post-quantum cryptography is a fascinating research challenge,and multivariate cryptography is one of the alternatives to guarantee the security of communication in the post-quantum world.The existing proxy ring signatures are based on the assumed hardness of big integer factoring problem and Discrete Logarithm problem which cannot resist quantum computer attack.So we design a new proxy ring signature scheme based on the MQ problem and IP problem of multivariate public key cryptography.It not only meets the requirements of proxy ring signature,but has benefits of quantum attack resistance,fast computing,and high efficiency.
