Abstract:The Secure Channel Free Public Key Encryption with Keyword Search (SCF-PEKS) scheme, which enables one to search for the encrypted keywords without leaking the privacy. In this paper, we point out the inefficiency of SCF-PEKS scheme and construct a new Located Secure Channel Free Public Key Encryption with Keyword Search (LSCF-PEKS) scheme to improve the efficiency. Furthermore, the LSCF-PEKS scheme is applied to implement cloud storage-oriented secure information gateway. At last, a bidding system is implemen… Show more
