Abstract: In this paper, we have proposed ciphertext policy attribute based encryption (CP-ABE), which is secured against the attack under the chosen encrypted message attack and indistinguishable under the chosen cipher text attack . On comparing with other schemes, it has the least energy consumption in terms of communication and computation. Based on the proposed CP-ABE, we have implemented a cloud-based internet of medical things enabled smart healthcare system. The healthcare system has achieved secure patients details, and public integrity of patient details stored on the cloud without revealing information to any third entity. Further, we have scrutinized the performance of the proposed health care system in terms of computation energy and communication energy consumption.
