| 20090063851 | ESTABLISHING COMMUNICATIONS - A method of establishing direct and secure communication between two wireless communications devices is disclosed. The wireless communications devices each have an existing trust relationship with an authentication server operable to authenticate access to a communication network on the basis of those existing trust relationships. The method comprises: (i) sending a communication request message directly from a first wireless communications device to a second wireless communications device; (ii) operating one of said wireless communication devices to request a symmetric encryption key from an authentication server; (iii) responsive to said request, operating said authentication server to: authenticate said one of said wireless communications devices on the basis of said existing trust relationship; generate said symmetric encryption key on successful authentication of said one of said wireless communications devices; and send said symmetric encryption key to said one of said wireless communications devices; (iv) responsive to receiving said symmetric encryption key, storing said symmetric encryption key at said one of said wireless communications devices and communicating it directly to the other wireless communications device; (v) securing direct communications between said wireless communications devices using said symmetric encryption key. | 03-05-2009 |

| 20110010762 | IDENTITY MANAGEMENT - In providing identity management in distributed systems, it is known to provide a user with a single sign-on to accounts with different service providers with whom the user interacts by communicating with the service providers' computers. Such a single sign-on is provided by having the user authenticate himself to an identity provider computer, and thereafter relying on that identity provider computer to issue identity assertions on his behalf. An identity provider validation service is proposed with which service providers can interact on receiving an identity assertion on behalf of a user. This allows the service provider to rely only on the identity provider validation service rather than having to rely on the numerous identity providers who might issue identity assertion on behalf of one of their users. Furthermore, the identity assertions include a level of assurance indication, and the identity provider validation service indicates whether each identity provider can be trusted to properly issue an identity assertion claiming that level of assurance. This provides a more fine-grained and adaptable identity management than has hitherto been provided. | 01-13-2011 |
