The Pouch uses a 64 x 64 block product cipher, a 1024 bit random initialization vector and the CBC technique. Most experts agree that such an implementation is highly resistant to all forms of cryptographic attack.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Wow! Resistant to those not invented yet - I guess this means one of two things - the pooch is a OTP, or Mr. Holt has a time machine.
Hellman and Dilfie rely on knowing the algorithm for their known plain text attacks
An unpublished algorithm forces them into reverse engineering the computer programs to learn the algorithm. The POUCH has many roadblocks built in to prevent this.
Wow! (again). Dongleless protection! I'm impressed. Now we don't need tamper resistant smart cards - we can do it all in software!
