EAP-TTLS
It is usually much easier to re-use existing authentication systems, such as a Windows domain or Active
Directory, LDAP directory, or Kerberos realm, rather than creating a parallel authentication system. As a result,
TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication
methods.”
TTLS and PEAP work in a similar way. First, they establish a TLS tunnel (EAP-TLS for example), and validate
whether the network is trustworthy with digital certificates on the authentication server. This step establishes
a tunnel that protects the next step (or “inner” authentication), and consequently is sometimes referred to as
“outer” authentication. The TLS tunnel is then used to encrypt an older authentication protocol that
authenticates the user for the network.
As you can see, digital certificates are still needed for outer authentication in a simplified form. Only a small
number of certificates are required, which can be generated by a small certificate authority. Certificate
reduction makes TTLS and PEAP much more popular than EAP-TLS.
The IE-WL-VL-AP-BR-CL provides some non-cryptographic EAP methods, including PAP, CHAP, MS-CHAP,
and MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However,
they may be useful as inner authentication methods with TTLS and PEAP.
Because the inner and outer
authentications can use distinct user
names in TTLS and PEAP, you can use
an anonymous user name for the
outer authentication, with the true
user name only shown through the
encrypted channel. Keep in mind that
not all client software supports
anonymous alteration. Confirm this
with the network administrator
before you enable identity hiding in
TTLS and PEAP.
