Teledyne (TET) is out marketing a "new" crypto system as a competitor against DES and what TET calls "linear" cryptosystems. They are claiming a non-linear approach in which (as best I can tell) they are permuting the s-boxes and using 4 bit/16 entry substitution tables.
Dont trust it unless you are a good cryptanalyst and have a copy of the source code. Most commercial crypto products are crap. Jonathan Wienke
