SIP, Security Mechanism, Authentication, Authorization, Audit, and AAA


Passive IP devices like SIP based surveillance camera, need to be secured due to the private information that it may transmit. This paper proposes an architecture to secure the information that the device could access in peer-to-peer overlay networks. This architecture provides the security mechanism for authentication, authorization and audit (AAA). It combines the security features of Authentication Servers with SIP architecture to provide AAA Service to registered users needing access to passive IP devices. Dynamic password for authenticating the access of the passive devices managed by the authentication server could be also applied to enhance the security features of devices.
