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.

Method and apparatus for using a bootstrapping protocol to secure communication between a terminal and cooperating servers

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.

Method and apparatus for private token communication services

This disclosure relates to a portable communication device and a network-side authorization server, and to methods therein. By splitting the functionality of an OAuth authorization server and moving the authorization endpoint into, for instance a mobile phone, an authorization server within the mobile phone is provided. This mobile phone authorization server does not need to communicate with the network-side for getting an authorization code or an access token.
