Abstract
Encrypted communications between peers are inspected by a proxy server, for bugs, viruses, malicious software and the like, while the proxy server is prevented from modifying the encrypted communications. A proxy server functioning as a gateway processor between the peers includes a security processor. The security processor is coupled to one of the peers via a channel that is separate from the channel carrying the encrypted communications between the peers. Cryptographic keys needed to decrypt the encrypted communications are provided via the separate channel to the security processor prior to commencement of encrypted communications. The security processor monitors the encrypted communications. The security processor decrypts the monitored encrypted communications without perturbing the encrypted communications. The security processor decrypts the encrypted communications utilizing the previously provided cryptographic keys. The security processor inspects the decrypted communications. If any faults are found, the security processor provides appropriate notification.
