Lightweight authentication and matrix-based key agreement scheme for healthcare in fog computing

Healthcare in fog computing is a novel topic in recent year. With the development of technology, it is a pressing issue to accomplish the secure healthcare in fog computing. Moreover, how to ensure the security and efficiency of the transmission healthcare data in open channel is a challenge to be solved. In this paper, a lightweight authentication and matrix-based key agreement scheme is proposed to support the communication of multi parties in fog computing. On the one hand, the lightweight authentication technology is needed to verify the identity of multi-parties that assure the facticity of communication parties in the open channel. On the other hand, using the matrix-based key agreement technology encrypts the healthcare data and uploads to the cloud server with the aid of the doubly-linked cyclic (DLC) tables. The security analysis shows that the proposed scheme is secure to transmit the data for healthcare. The performance analysis shows that the proposed scheme reduces the communication cost.
