Fog computing is a new distributed computing paradigm that extends cloud services to the edge of the network, with features such as mobile support, location awareness, and low latency. Identity authentication in fog computing should support user mobility. For this reason, this paper proposes an anonymous handover authentication scheme for fog computing, FogHA, which achieves mutual authentication and key agreement between the adjacent fog node and the mobile device. FogHA only uses lightweight cryptographic primitives and eliminates redundant a...
