摘要:
A method of managing revocation when an alternate transmission method, using an alternate transmitter identity and an alternate receiver identity, is juxtaposed into an original transmission system, the original transmission system having its own original transmitter and receiver identities that communicate via an original transmission method involves at an alternate transmission receiver (ATR), providing a digital certificate, the digital certificate cryptographically binding the ATR identity to an original transmission (OT) re-transmitter identity; at the ATR, responsive to an initiation of a communication session from an alternate transmission transmitter (ATT), sending the digital certificate to the ATT using the alternate transmission method; at the ATT, extracting the original transmission identity from the certificate and sending it to the original transmission transmitter (OTT) using the original transmission method for checking in a revocation list; and if the OT identity is found to be in the revocation list, preventing copy protected content from being sent from the OTT. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
