An improved asymmetric searchable encryption scheme

Abstract

Data to be uploaded on the cloud storage system will often be encrypted for security reasons. No classic encryption & decryption algorithms however provide any search function. To increase user efficiency, an asymmetric searchable encryption scheme is designed in this paper. This improved scheme aims at fixing such flaws as “trapdoors that can be generated by anyone”, “ciphertexts that are tampered with at discretion”, “key pairs generated by users”, “identities encrypted” and “a useless component”. Findings suggest that the proposed scheme, while maintaining the established framework, perfectly resolves all the aforementioned flaws in the previous scheme.
