LOGO Encryption

-----------

ATOMIC-2 is investigating mechanisms for high-speed encryption and authentication. We have investigated the following authentication mechanisms, and have not found one suited to 640 Mbps implementation, as well as implementation in software that can keep pace with IP over ATOMIC speeds (140 Mbps).

* MD5

MD5 is an authenication algorithm proposed as a "required option" for the next IP (IPv6).

* Alternate Hash Algorithm (AHA)

The Alternate Hash Algorithm is designed as a replacement for MD5 in IPv6. AHA runs over twice as fast as MD5.
