摘要: 针对现有的带关键词检索的公钥加密(PEKS)方案中的大量对运算需要消耗较多时间,且都存在不能抵抗重放攻击的问题,在研究PEKS的基础上,提出一种高效的带关键词检索的公钥加密方案。与现有的PEKS方案相比,该方案保留了现有PEKS方案的优点,能有效地抵抗重放攻击。

关键词: 公钥加密, 带关键词检索的公钥加密, 高效率

Abstract: Aiming at the problems of great computation of pairings in Public key Encryption with Keyword Search(PEKS) schemes are still time consuming and inefficient, and the proposed PEKS schemes can not resist to relay attacks, on the base of researching the PEKS, this paper proposes a more efficient PEKS scheme. Comparing with the previously mentioned PEKS schemes, the new PEKS scheme retains the advantages of the previously one and it is more simple, efficient and resistible.


Key words: public key encryption, Public key Encryption with Keyword Search(PEKS), high efficiency
