A CPK-Based Identity Authentication Scheme for IoT

As the power Internet of Things (IoT) enters security construction stage, massive use perception layer devices urgently requires an identity authentication scheme that considers both and practicality. The existing public key infrastructure (PKI)-based is currently difficult to apply in many terminals IoT. Its distribution management costs are high, which hinders development IoT construction. Combined Public Key (CPK) technology uses a small number seeds generate unlimited keys. It very suitable for Things. In this paper, we propose novel combines physical unclonable function (PUF) with improved CPK achieve mutual between servers. proposed does not require third-party improves Moreover, reduces resource consumption devices. algorithm solves collision problem, third party only needs save private matrix. Experimental results show amount storage resources occupied our small. more
