Design of embedded secure gateway based on 6LoWPAN

The paper proposes an embedded security gateway based on 6LoWPAN, which connects wireless sensor network with IPv6 network. Users can query current data of a certain sensor or historical data. The user authentication and SNEP security mechanism provide good secure guarantee to communication between networks; the address translation mechanism transforms an IPv6 address into a short address, which improves communication efficiency in 6LoWPAN network. The experimental results show that the design of gateway can realize communication authentication and security between the gateway and sensor node, and it balances performance and security.
