A security system and a method for ubiquitous networks are provided to realize a security protocol model with a telematics technology. A method for ubiquitous networks includes the steps of: subscribing to one specific network region of the ubiquitous networks; obtaining authentication in the one specific network region by performing a single sign on procedure with corresponding key authentication; and accessing one or more other network regions of ubiquitous networks according to the authentication obtained from the one specific network region.
