Security analysis and improvement of KNXnet/IP protocol
Zhang Xi-huang · Journal of Computer Applications · 2011
As the extended application of European Installation Bus(EIB) protocol,KNXnet/IP protocol increases the transmission speed of EIB system and fulfills the requirement of intelligent management.But the security of KNXnet/IP protocol is heavily threatened in the security-critical environment.A security protocol was proposed after analyzing the security mechanism of IP network and embedded system.The security protocol used self-defined key sets distribution protocol based on asymmetric cryptography algorithm and used symmetric cryptography algorithm for communication.It provides transparent data transmission and only needs very few changes of the primary architecture.The implementation proves the feasibility and security of the security approach.
