An effective device and data origin authentication scheme in home networks
Soobok Shin, Hongjin Yeh, Kangseok Kim · 2012
Home network provides residents with autonomous services for convenient and secure life through communication among networked home devices. Particularly, as services of home network are provided through communication among home devices without human intervention, device and data origin authentication among devices are important for secure home. Most home devices do not have restrictions such as power supply and networking because home devices are located in home. On the other hand, home devices have the restrictions of computing power and memory capacity. Therefore security in home network should be designed effectively considering those restrictions. In this paper we propose device authentication scheme for secure home network. The proposed scheme does not have high computation complexity due to applying low cost operations such as hash function and exclusive-OR. Also the proposed scheme proposes mutual authentication and data origin authentication and then we show that our scheme is secure through security analysis.
