ABSTRACT:

In the place of searchable encryption, the searchable public key encryption (SPE) is an attractive technique in cozy cloud storage. SPE assures the facts confidentiality without affecting the usage of the records stored inside the cloud. Furthermore, compared with the symmetric searchable encryption, SPE does not require key distribution and control. We investigate the safety of the searchable public key encryption based on the conventional Boneh’s framework. Although present SPE schemes can allow customers to search over encrypted information, maximum of those schemes are prone to the record-injection assault and the insider keyword guessing attack. To mitigate these assaults, we advise an green and secure searchable public key encryption with privateers safety (SPE-PP). We then provide a concrete construction of SPE-PP that makes use of the Diffie–Hellman shared secret key, and we show it can face up to those attacks. Both the theoretical analysis and the experimental results display that our scheme achieves robust security together with high efficiency.
