摘要
对Du等提出的无证书、短签名方案进行分析与改进,设计了一个将双线性映射和密钥交换技巧有效结合起来的数字签名方案.该方案的一个重要特性就是对秘密信息有效性的公开验证,同时保持了原方案的短签名等特点,在公开且低带宽的通信环境下更适于应用.
The Duet al certificateless short signature scheme was improved and a short signature scheme was presented, which combined bilinear pairings with key exchanging. An important new feature in the proposed scheme was public verifiability on the correctness. It could also shorten the total lengthen of the signature pair like in the Duet al's paper. So it can be widely used, especially in low-bandwidth communication environment.
