As a very attractive cryptographic primitive, the public key encryption with keyword search (PEKS) enables users to search on encrypted data, and hence is applicable to the setting of cloud computing. Although the existing PEKS schems can allow a user to search encrypted data confidentially, most of them failed to verify the searched result and the system(More)
The nano-Bi2WO6/reduced graphene oxide composite obtained by a simple hydrothermal reaction demonstrates a larger specific capacitance of 922 F/g at a charge and discharge currents of 3 A/g with longer cycle life. The As comparison, pristine Bi2WO6 nanoparticles have poor specific capacitance of 574 F/g at a charge and discharge currents of 2 A/g with weak(More)
