抗泄漏的基于身份的分层加密方案

在秘密信息泄漏的情况下,设计出安全的密码系统就成为当前迫切需要解决的一个问题.为此,构造出了一个可以抗私钥泄漏的分层的基于身份的加密方案,通过双系统加密和哈希证明系统方法证明了系统的安全性,通过使用提取器得到所给的方案是抗私钥泄漏的.该方案的抗泄漏性能与层数有关,当只有一层时,相对泄漏率可以达到1/3....

When the secret information leak,to design cryptographic systems with security has become an urgent problem needed to be solved for cryptographers.This paper presented a hierarchical identity-based encryption scheme which was resilient to the private key leakage.It used the dual system encryption method to prove the security of the presented system.It used the hash proof system method to prove that the scheme was resilient to the private key leakage.The performance of leakage-resilience is related to layers.When only one layer considered,the relative leakage rate could reach 1/3.
