Re: Deffi-Helmen Group Vs DES or 3DES or AES

DES, 3DES & AES are encryption mechanisms by which the devices. These use a shared key to encrypt data.

Diffie-Helman is a mechanism by which the devices determine the shared key. The number refers to the number of times the result is removed from the initial calculation.

There is not a bad (but in depth) description on wikipedia
