Public Key Encryption with Keyword Search (PEKS) scheme enables one to search the encrypted data with a keyword without revealing any information. The concept of a PEKS scheme was proposed by the researchers in 2004 and who extended PEKS scheme into a Secure Channel Free PEKS scheme (SCF-PEKS) which removes the assumption, a secure channel between users and a server. In this paper, the authors show an overview of six existing security models of PEKS/SCF-PEKS scheme and conclude five security requirements that must satisfy to construct a secure PEKS/SCF-PEKS scheme.
