Okay, we can remove it, no pb.
Just fyi, 3DES EDE was also proposed because it is already used in the
BPI+ spec for the traffic encryption key (TEK). See page 21 of BPI+ at
http://www.cablemodem.com/downloads/specs/BPI+_I11-040407.pdf :
"The traffic encryption key (TEK) in the Key Reply is triple DES
(encrypt-decrypt-encrypt or EDE mode) encrypted, using a two-key, triple
DES key encryption key (KEK) derived from the Authorization Key."
This should close the threads on your comment - thank you again for the
review.
