Public Key Encryption with Keyword Search Revisited.
Joonsang Baek, Reihaneh Safavi–Naini, Willy Susilo · 2005
The public key encryption with keyword search (PEKS) scheme recently proposed by Boneh, Di Crescenzo, Ostrovsky, and Persiano enables one to search encrypted keywords without compromising the security of the original data. In this paper, we address three important issues of a PEKS scheme, "refreshing keywords", "removing secure channel", and "processing multiple keywords", which have not been considered in Boneh et. al.'s paper.
