An Authentication Scheme with Attribute-Based Encryption for Power Internet of Things

Power Internet of Things(PIot) has absorbed edge computing technology, reducing the computing pressure of cloud service centers and providing intelligent services for edge devices through edge server. Due to the computing resources constraints,unattended and widely distributed of end devices,attacks on edge devices and edge servers are becoming more frequent.Attribute-based encryption can provide a higher level of protection for the edge computing model and a more flexible operation relationship. In the current attribute-based encryption scheme, the attributes assigned by the cloud server to the edge device are not authenticated, which may lead to the situation that the assigned attributes are stolen. we propose an identity authentication scheme that can authenticate for attributes. The scheme realizes mutual authentication between edge devices and edge servers. It combines attributes and ID to authenticate, thereby avoiding the misuse of attributes. This scheme can provide higher security without affecting the efficiency.
