SCF-PEPCKS: Secure Channel Free Public Key Encryption With Privacy-Conserving Keyword Search

Adaptive Secure-Channel Free Public-Key Encryption with Keyword Search Implies Timed Release Encryption

As well-known results, timed-release encryption (TRE) and public key encryption scheme with keyword search (PEKS) are very close to identity-based encryption (IBE), respectively. It seems natural that there is a close relationship between TRE and PEKS. However, no explicit bridge has been shown between TRE and PEKS so far. In this paper, we show that TRE can be generically constructed by PEKS w...

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...

Secure Keyword Search with Public Key Encryption by Cloud storage

Public Key Encryption with Conjunctive Field Free Keyword Search Scheme

Searchable encryption allows a remote server to search over encrypted documents without knowing the sensitive data contents. Prior searchable symmetric encryption schemes focus on single keyword search. Conjunctive Keyword Searches (CKS) schemes improve system usability by retrieving the matched documents. In this type of search, the user has to repeatedly perform the search protocol for many t...
