Raza, Shahid and Voigt, Thiemo and Roedig, Utz (2011) 6LoWPAN Extension for IPsec. In: Proceedings of the IETF-IAB International Workshop on Interconnecting Smart Objects with the Internet :. .
Real-world deployments of wireless sensor networks (WSNs) require secure communication. Recently, WSNs and traditional IP networks are more tightly integrated using IPv6 and 6LoWPAN. Available IPv6 protocol stacks can use IPsec to secure data exchange. Thus, it is desirable to extend 6LoWPAN such that IPsec communication with IPv6 nodes is possible. It is beneficial to use IPsec because the existing end-points on the Internet do not need to be modified to communicate securely with the WSN. We propose a 6LoWPAN extension for IPsec. Our extension supports both IPsec’s Authentication Header (AH) and Encapsulation Security Payload (ESP). Thus, communication endpoints are able to authenticate, encrypt, and check the integrity of messages using standardized and established IPv6 mechanisms.
