Public Key Encryption with Keyword Search (PEKS)
scheme enable one to search the encrypted data with a
keyword without revealing any information. The concept
of a PEKS scheme was proposed by Boneh et al. in 2004
and Baek et al. 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, we show an overview of six existing security models of PEKS/SCF-PEKS scheme and
conclude ¯ve security requirements that must satisfy to
construct a secure PEKS/SCF-PEKS scheme. Then we
compare the security and e±ciency of the security models
and discuss the future researches of PEKS/SCF-PEKS. Public Key Encryption with Keyword Search (PEKS)
