Abstract

A network device may decrypt a record received from a source device and associated with an encrypted session. The network device may process the decrypted record. The network device may encrypt the record to generate an encrypted payload. The network device may store an entry in a retransmission mapping that includes a decryption key used to decrypt the record and an encryption key used to encrypt the record. The network device may transmit the encrypted payload in a first TCP packet toward the destination device. The network device may receive retransmitted data and may determine, based on the record entry, that the retransmitted data is associated with the record. The network device may decrypt, using the decryption key, the retransmitted data and may re-encrypt, using the encryption key, the decrypted record. The network device may transmit, toward the destination device, the encrypted payload in a second TCP packet.
