1. A method, comprising:

  • distributing one or more session keys from a key distribution point to establish a secure communication session between a first endpoint and a second endpoint;

    establishing a secure channel between the key distribution point and a first intercepting endpoint using an authentication protocol;

    determining, by one or more hardware processors of the key distribution point, that the first intercepting endpoint is authorized to intercept the secure communication session by determining that an interception rule stored in memory authorizes the first intercepting endpoint to receive at least one of the session keys; and

    in response to determining that a request to intercept the secure communication session by the first intercepting endpoint is authorized, transmitting, from the key distribution point to the first intercepting endpoint, the session key, the session key providing the first intercepting endpoint with access to intercept the secure communication session.
