esGate: Secure embedded gateway system for a wireless sensor network

In this paper, we propose a secure embedded gateway system for a wireless sensor network that provides secure wireless and wire communication channels for wireless sensor nodes and applications in the Internet, respectively. It also has security functions such as key management, access control and secure wireless network configuration for wireless sensor nodes and secure query process for its applications. Consequently, the esGate is capable of achieving original purposes of wireless sensor network gateway with enhanced security properties which are securely gathering and transmitting information such as sensor events, control commands and security data from wireless sensor nodes to applications, and vice versa.
