Public key encryption with keyword search secure against keyword guessing attacks without random oracle

Public key encryption with keyword search secure against keyword guessing attacks without random oracle

The notion of public key encryption with keyword search (PEKS) was put forth by Boneh et al. to enable a server to search from a collection of encrypted emails given a “trapdoor” (i.e., an encrypted keyword) provided by the receiver. The nice property in this scheme allows the server to search for a keyword, given the trapdoor. Hence, the verifier can merely use an untrusted server, which makes...

A Secure Channel Free Public Key Encryption with Keyword Search Scheme without Random Oracle

The public key encryption with keyword Search (PEKS) scheme, proposed by Boneh, Di Crescenzo, Ostrovsky and Persiano, enables one to search for encrypted keywords without compromising the security of the original data. Baek et al. noticed that the original notion of PEKS requires the existence of a secure channel, and they further extended this notion by proposing an efficient secure channel fr...

Post-Quantum Secure Public Key Broadcast Encryption with Keyword Search

In remote data storage system, the information privacy is the main concern of the users. Data confidentiality, keyword search and access control are important characteristics that should be supported in such system. With the advent of quantum computer, number theory related assumptions are vulnerable to quantum attack. In this context, we propose a post-quantum secure searchable encryption sche...

Public Key Encryption with Keyword Search Revisited

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 c...
