XIP7013E implements the IPsec (Internet Protocol Security) protocol ESP (Encapsulating Security Payload) packet processing using AES-256-GCM with a streaming interface. The IPsec protocol defines a security infrastrucure for Layer 3 (as per the Open System Interconnect (OSI) model) traffic by assuring that a received packet has been sent by a transmitting station that claimed to send it. Furthermore, the traffic between stations is both encrypted to provide data confidentiality and authenticated to provide data integrity.
