1.1.2 AES EAX
Description
EAX mode was submitted on October 3, 2003, to NIST by Mihir Bellare, Phillip Rogaway, and David Wagner. It utilizes AES-CTR mode for encryption and AES-OMAC for authentication. In EAX mode, authentication is provided over additional associated data (AAD), while both confidentiality and authentication are ensured over the plaintext data. This demo application demonstrates the functionality of Crypto v4 AES-EAX functions.
