Abstract :
In SOK key distribution scheme, the shared key for safe channel can be generated without any interaction between two entities. But the shared key will be never update through life period of Key Generate Center (KGC) that cause more attacked risks. In this paper, we propose improved key distribution scheme and key update scheme to overcome the shortage of SOK scheme which are also non-interactive. Last, security analysis on the improved schemes above is given.
