More and more devices could provide SIP-based VoIP, but most of them only support non-encrypted sessions. Some of the soft phones support the establishment of secure sessions, but they may not be compatible to other soft phones.

In this thesis, a secure architecture is proposed in the home/office networking environment. A special appliance, called Building Security Gateway (BSG), is designed to help weak SIP devices to perform security functions, such as initialization of secure sessions and encrypting/decrypting media similar to PCs. Furthermore, a prototype BSG is built in a home/office network, and BSG-based session mobility cases between UAs are constructed and the related protocol primitives are discussed. BSG could monitor the passing-by encrypted sessions and recover them into decrypted ones.

In this thesis, a secure architecture is proposed in the home/office networking environment. A special appliance, called Building Security Gateway (BSG), is designed to help weak SIP devices to perform security functions, such as initialization of secure sessions and encrypting/decrypting media similar to PCs. Furthermore, a prototype BSG is built in a home/office network, and BSG-based session mobility cases between UAs are constructed and the related protocol primitives are discussed.

The BSG architecture could help devices set up secure sessions and provide the monitoring functionality at the same time.
