Abstract

Efficient Public key encryption with key word search (EPEKS) enables
user Alice to send a secret key to a server that will enable the server to
locate all encrypted messages containing the keyword, but learn nothing
else. We have already published a previous paper explaining this scheme
the Efficient Public Key Encryption with Keyword Search (EPEKS). In
this paper, we focused on the relationship between the security and
(EPEKS). Firstly we briefly review the construction of this scheme
(EPEKS). (EPEKS) doesn’t base on Identity Based Encryption or pairing
which was used in the construction of the (PEKS) that proposed in
Boneh’s paper and other papers; it is based on Public Key Cryptosystem.
Secondly, we explained and compared between previous published
papers and clarified the relationship between security and (EPEKS).
Finally, we mentioned the encryption mechanisms regarding the system.
