| 摘 要： | 分别对已有文献提出的两种没有双线性对的无证书签名方案进行分析,发现王方案虽然算法简单,效率高,签名长度短,但安全性低;陈方案安全性虽高,但计算量大,效率较低,签名长度长,在要求带宽较低的无线网络环境中不实用.为克服两种方案的缺点,提出一种新的没有双线性对的无证书签名方案,新方案算法简单,效率高,签名长度较短,在离散对数问题难解的情况方案证明是安全的.

| Abstract: | By analyzing two certificateless signature schemes without pairing proposed by Wang and Zhang respectively,found that although the scheme proposed by Wang was simple,efficient and the length of the signature was abbreviatus,the security of the scheme was not high;The similar scheme proposed by Chen was proved security,but had more calculatedamount,inefficiency,and longer signature.So Chen's scheme was not adaptable in the environment of wireless.To remove the weakness of the two schemes,the paper proposes a... |
