Authentication Protocols for Service Mobility Using Forward Secrecy Cryptosystems
SoYeon LIM, Hiroyuki Morikawa (Univ.of Tokyo) MoMuC2007-23
Abstract (in Japanese) (See Japanese page) 
(in English) Service mobility is spotlighted on the need to retain access to service across different devices and networks in ubiquitous computing environment. To support service mobility, there are two security problems to be solved. One is forward secrecy caused by service migration to insecure devices, which are public or belonging to another. The secret key on insecure devices can be accessed by adversaries. We introduce forward secrecy cryptosystems, key-insulated and identity-based public key cryptosystem are introduced in authentication protocols. The other problem is non-fixed reliable parameter between two end points. It is need any non-volatile parameter even if a service roams among diverse devices across networks. We classify authentication protocol into user and device authentication to share a session_id as an identity parameter over the service session. We propose authentication protocols considering above-mentioned and compare them.
