摘要： 针对边信道攻击引起密码系统秘密信息泄漏问题，提出抗密钥泄漏且支持属性撤销的密文策略的属性基加密方案。提出的方案具有完全安全性。基于双系统加密技术，给出的方案在标准模型下是可证安全的。该方案不仅可以抵抗私钥的泄漏而且也可以抵抗主密钥的泄漏。此外，给出的方案通过密钥的有效更新还可以抵抗密钥的持续泄漏。

Abstract: In order to solve the problem of information leakage incurred by side channel attacks, the paper presents a leakage resilient ciphertext-policy attribute-based encryption supporting attribute revocation. The scheme is fully secure. Based on dual system encryption technology, the scheme is proved to be secure in the standard model. This scheme can resist information leakage not only from the private key but also from the master key. In addition, the proposed scheme can resist continuous information leakage by the key update algorithm.
