US Patent 11349821 System and process for TLS exceptionally verified eavesdropping

Although TLS provides desirable end-to-end encryption, there are circumstances in which it is desirable or a regulatory requirement for a client to establish a TLS connection through an intermediary that is capable of creating an archival record. There is provided a modification to the TLS protocol that allows an aware client to provide a recovery record to such an intermediary. The recovery record permits the intermediary to verify that the encrypted recovery records can be decrypted by a party that holds the corresponding private key but does not enable decryption by the intermediary.
