An Authentication Mechanism for IoT Devices Based on Traceable and Revocable Identity-Based Encryption.

To solve low computing efficiency and high computational energy consumption in the traditional Public-key Infrastructure cryptosystem in the authentication of IoT devices, an authentication scheme for IoT devices based on the Identity-based Encryption is proposed in this paper, which is realized by introducing traceable and revocable mechanisms. The effective management of the secret key of the suspicious devices by the authentication center and the reasonable accountability of the dishonest private key generator (PKG) are realized. Finally, through the security proof, it is verified that the Identity-based Encryption designed in this paper can meet the security of the Chosen Ciphertext Attack (CCA), indicating that the scheme has high practicability and security.
