报告摘要：Authenticated key exchange (AKE) is a significant procedure in protecting wireless communications. Typical solutions combine the Elliptic Curve Diffie-Hellman (ECDH) key exchange scheme with authentication measures. However, the majority of existing protocols require equivalent computations on the two devices even if they have fairly different computational capabilities. Therefore, they are not friendly to computationally limited devices which exist widely in wireless communications.In this talk, I will introduce a method to customize the ECDH-based AKE according to the computational capability of devices. In particular, the method shifts some time-consuming computations from the computationally limited device to the more powerful one.
