The RFC specifications for the RADIUS protocol dictate that RADIUS:
Is a UDP-based connectionless protocol that doesn’t use direct connections
Uses a hop-by-hop security model
Is stateless (more to come on that later)
Supports PAP and CHAP authentication via PPP
Uses MD5 for password-hiding algorithms
Provides over 50 attribute/value pairs with the ability to create vendor-specific pairs
Supports the authentication-authorization-accounting model
In addition, RADIUS enjoys support by virtually every commercially available NAS product, ensuring its future well into the next 10 years.
