摘要

Modern cloud computing environments require strong cryptographic solutions to ensure data confidentiality and security against quantum computing threats. This work proposes a new cryptographic framework that combines Supersingular Isogeny Diffie–Hellman (SIDH) with certificateless hashed public key authenticated encryptions with keyword search to improve the need of security and efficiency in cloud computing environments. The majority of conventional cryptographic solutions have vulnerability under quantum computing attacks and inefficiency in key management and keyword search. This framework has exploited SIDH to overcome the drawbacks of the approaches. By exploiting the inherent computational difficulties in isogenies between supersingular elliptic curves, strong post-quantum security is gained. It assures the system against the classical and quantum threats. Searching on encrypted data using SIDH with CL-HPAEKS is more secure and efficient. CL-HPAEKS aims at providing a certificate-less secure keyword search system to eliminate the overhead associated with certificate management while keeping high security standards. The result shows an average time to be around 534–4334 ms for encryption and from 812 to 4041 ms for decryption, depending on the size of data.
