Abstract
Encrypted data packets are received by a network interface card. The network interface card, upon determining that the received data packets are encrypted, directs the encrypted data packets to decryption hardware in the network interface card. The decryption hardware decrypts the encrypted data packets and forwards the decrypted data packets to a hardware classifier that classifies the decrypted data packets and directs the classified decrypted data packets to the appropriate receive resource(s) of the network interface card.
