Expressive And Effective Public-Key Searchable Encryption Scheme Over Encrypted Data Of Cloud Store In The Prime-Order Groups

Abstract

Searchable cryptography permits a cloud server to conduct keyword search over encrypted information on behalf of the information users while not learning the underlying plaintexts. However, most existing searchable cryptography schemes solely support single or conjunctive keyword search, whereas a number of different schemes that square measure ready to perform communicatory keyword search square measure computationally inefficient since they're engineered from additive pairings over the composite-order teams.
