An efficient IoT group association and data sharing mechanism in edge computing paradigm

Despite its benefits and promising future, security and privacy challenges for the IoT wireless communication of edge computing environment remain unaddressed. As a result, proper authentication mechanisms are critical, especially in the extreme scenario where some edge facilities are not functional. For the above consideration, in this paper we develop an efficient IoT group association and updating mechanism in edge computing paradigm. The proposed scheme can provide data transmission and communication guarantees for special practical scenarios. The group key updating process in our architecture only necessitates minor changes on the EI side, whereas the decryption information of some IoT devices remains constant if the devices have not been revoked. The proposed strategy can accomplish the desired security features, according to the security analysis.
