Abstract
Methods and apparatus for protecting user privacy in a shared key system. According to one aspect, a user generates a derived identity based on a key and a session variable, and sends the derived identity to an application. In one embodiment, a key server may be used to receive the derived identity from the application, and return a sub-key to the application to use for encrypting communications with the user.
