Abstract
In some implementations, a method for providing a session key to a third party includes identifying a private key associated with a public key certificate in response to an event. A session key for a communication session is based, at least in part, on the private key, an associated seed for a random number generator, and public keys assigned to user equipment participating in the communication session. The private key associated with the public key certificate is automatically transmitted to an interception authority. The interception authorities are configured to grant a third party access to the private key and the associated seed to in response to a request from a third party authorized to access the communication session.
