A design of the lightweight key management system for multi-level embedded devices

Abstract Embedded devices often face security risks such as device loss, cracking, key disclosure and side-channel attacks. Owing to the relative meagreness characterising availability of computing well storage resources, it might be said that embedded themselves have limited traditional management solutions are thus not fully suitable for usage scenarios. In addition, also necessitates consideration dynamic changes devices, joining withdrawal, blacklist control. A lightweight scheme is proposed multi-layer control problems library analysed an optimisation proposed. Finally, this paper in detail based on aspects resource overhead. Compared with scheme, designed can better applied communication meet requirements systems.
