--------------------------------------
Type: Technical
Reported by: Manav Bhatia <[email protected]>

Section: 4.5

Original Text
-------------
If the Protocol-Specific Authentication Key (Ks) is L octets long, then Ko is 
equal to K. 

Corrected Text
--------------
If the Protocol-Specific Authentication Key (Ks) is L octets long, then Ko is 
equal to Ks. 

Notes
-----
The key K is never used in computing the digest. There is a class of cross 
protocol attacks that can be prevented if the original key K is appended with a 
few well known bytes. As a result, the key K is appended with a 2 octet crypto 
protocol ID to derive a new key Ks. Its this key that must always be used.
