基于hash函数的一次群签名模型
One-time group signature model based on hash function
摘要
Abstract
Since traditional digital signature based on the big integer prime decomposition and discrete logarithm problem can't resist attack in quantum computing,this paper proposed a signature model based on the hash function. The security of this model is based on the hash function is unidirectional. Its key generation, signature and verification are completed by hash computing. This model could help achieve higher efficiency, and resist attack in quantum computing effectively. Proved by ex-periments, its efficiency is 21 times higher than ECC (a key length for 224), and can reach 102 limes higher than RSA-2048.关键词
