Public key authenticated encryption with multiple keywords search using Mamdani system

The public cloud environment has attracted massive attackers to exploit insecure ports and access data, services other resources. Techniques, such as Public Key Encryption with Keyword Search (PEKS), could be deployed in security avoid accidents. PEKS allows users search encrypted documents by a specific keyword without compromising the original data security. first scheme was proposed 2004, since then, been experienced great progress. Recently, Kazemian Ma firstly incorporated Fuzzy Logic technique scheme, namely “Public Multi-keywords using Mamdani System (m-PEMKS)”, order support (i.e. “latest”, “biggest”) Search. However, m-PEMKS ability prevent Off-line Guessing Attack (OKGA) but it may suffer Inside (IKGA). This paper will revisit propose robust mechanism. properties of Ciphertext Indistinguishability, Trapdoor Indistinguishability User Authentication which can OKGA IKGA. Besides, supports both Multiple Keywords therefore, is more practical applied general networks.
