Encryption
Data Encryption Standard (DES) and Triple DES (3DES) are supported for encryption.
• DES is a widely-used method of data encryption using a private (secret) key. Both the
sender and the receiver must know and use the same private key.
• 3DES is a more secure version of the DES protocol.
802.1x Network Access Control
The Alcatel-Lucent OS supports network access control of client devices (PCs, STBs, etc.) on
an Ethernet network using the IEEE. 802.1x standard. 802.1x is known as Extensible
Authentication Protocol (EAP) over a LAN network or EAPOL.
TCP Enhanced Authentication Option
The TCP Enhanced Authentication Option, currently covered in draft-bonica-tcp-auth-05.txt,
Authentication for TCP-based Routing and Management Protocols, extends the previous
MD5 authentication option to include the ability to change keys without tearing down the
session, and allows for stronger authentication algorithms to be used.
