【Abstract】 The security architecture of IEEE standard 802.15.4-2003 in Low-Rate Wireless Personal Area Networks (LR-WPAN) mainly comprises security mode, ACL entry and security services. As the highest security level, the implementation method and time consumption of AES-CCM in 802.15.4 are discussed. In addition, the working environment is resource restricted such as the low memory and computation. The different security functions required by a wide variety of applications make the tailorable and hierarchi-cal structure critical in security architecture.更多还原
