Abstract: A method comprising the use of a bootstrapping protocol to define a security relationship between a first server and a second server, the first and second servers co-operating to provide a service to a user terminal. A bootstrapping protocol is used to generate a shared key for securing communication between the first server and the second server. The shared key is based on a context of the bootstrapping protocol, and the context is associated with a Subscriber Identity Module (SIM) associated with the user terminal and provides a base for the shared key. A method of the invention may, for example, be employed within a computing/service network such as a “cloud”, and in particular for communications between two servers in the cloud that are co-operating to provide a service to a user.

Abstract: Rather than forcing users to give personally identifying contact data to information providers, this disclosure teaches an apparatus and method enabling the use of “private tokens,” which allow information providers to send electronic communications to targeted users without having access to personally identifying contact information. These features are provided by an anonymous communication service that manages the private tokens and provides communication proxy services intermediating the electronic communications between the information providers and the users targeted by those communications.

Abstract: In the first embodiment, the mobile phone 20 obtains the PCID from the CCE 10, and sends the PCID and the IMSI of the USIM of the mobile phone 20 to the CAPS 50. The MCC+MNC part of the IMSI is later used as the operator identification information by the mediation server 30, which is operated by the RO, in order to identify the SHO for the CCE 10. The MSIN part of the IMSI is later used as the user identification information by the account managing server 40, which is operated by the SHO, in order to identify the user of the mobile phone 20. The mediation server 30 forwards the account request from the CCE 10 to the account managing server 40 of the SHO identified by the operator identification information. The account managing server 40 generates the MCIM that is associated with the user identified by the user identification information.
