Abstract

Intercepting a secure communication session includes distributing a key from a key distribution point to establish a secure communication session between a first endpoint and a second endpoint. A secure channel is established between the key distribution point and an intercepting point. The intercepting endpoint may be determined to be authorized to intercept the secure communication session. The key is provided to the intercepting endpoint only if the intercepting endpoint is authorized to intercept the secure communication session, where the key provides the intercepting endpoint with access to intercept the secure communication session.
