摘要 支持多关键字检索的公钥加密(PEMKS)是支持关键字检索的公钥加密(PEKS)的扩展,能够支持接收者对嵌入密文中的所有关键字的子集进行检索。针对公钥加密中的多关键字检索以及密文长度问题,利用内积加密方案构造一个支持多关键字检索的公钥加密方案并给出安全性分析。 Public-key encryption with multi-keyword search（PEMKS） is the extension of the public-key encryption with keyword search（PEKS）,it can support the receiver to search all subsets of Key words embedded in the ciphertext.In this paper,we construct a PEMKS scheme by using inner-product encryption（IPE） scheme aiming at the problems of multi-keyword search in public key encryption as well as ciphertext length,and give the security analysis on it.
