基于前向安全签名体制的研究及其应用

Research and Applications of Signature Cryptosystem based

对前向安全签名体制进行了研究,提出了一种新的前向安全的签名算法。该算法能同时满足签名密钥的更新与签名的前向安全,具备了更高的前向安全性.从而最大限度的减少了私钥泄漏所造成的危害。把该算法应用到交叉认证及电子商务等网上办公系统方面,不但可以提供更高的安全性,而且可以大大地提高办公系统的效率。

A new forward-secure digital signature is proposed by researching on the forward-secure signature cryptosystem.It ensures that both the update of the signature's secret key and the signature are secure,which has higher forward-secure.Thereby,the loss caused by leaking key is reduced to the minimum degree.Moreover,this algorithm is applied to the web office system such as cross authentication 、E-commerce and so on.It not only can offer higher security but also largely improve the efficiency of the office sys...
