混合加密体制在数字签名中的应用

Application of hybrid encryption system in digital signature

为了进一步提高现有数字签名技术的安全性,同时为以后密码学的发展提供一个新的角度,提出了混合加密的思路,提出了一种实现不同结构加密算法的融合思想。将ECC算法与传统的RSA算法结合起来,在结构上进行优化组合,应用于数字签名中去。该方案跳出了从结构上差异较大的局限,选择了二者相似的密钥数据结构的角度对算法进行混合。从理论上来说,该方案可以在安全性和运行开销上取得最优化的结果。

In order to improve the safety of the current digital signature systems, and provide a new sight for the development of cry- ptosystem, here a new thought of hybrid encryption, and the thoughts of how to fuse the algorithms which has different structures are presented. So we combine the ECC algorithm with the RSA algorithm, and make the structure optimiz. Then it avoids the limit of different structures, and uses the sameness of their keys＇ data organizations to be combined. In theory, the optimization balance point between security and the cost can be found.
