Abstract :
This paper presents a new key update scheme which is different from the existing ones, the complete private key is not required to be stored in the sensor node, a new update method based on elliptic mapping is proposed, by which the computation consumption is reduced and the security of the terminal node in IoT is improved, the experimental test with practical hardware sensor node is given to show the effectiveness of the proposed method.
