In this paper, a new method of identity-based encryption is first presented, and it is shown that there is less computational overhead than previous methods. In this regard, the proposed identity-based encryption method is simulated, and the results are compared with the superior representatives of the identity-based encryption. Then, a cloud-based electronic health system (EHS) is proposed using the re-encryption proxy and the identity-based encryption method presented in this paper. In addition to providing confidentiality and enhancing accessibility, the system has a lower running time in the phases of setup, private key generation, encryption, re-encryption key generation, and decryption — this resulting in lower costs and overhead of the cryptographic process in the Electronics health system.
