Encryption Package
by 3C

Software Overview

The security of stored and transmitted data is a matter which becomes increasingly important. To 
meet the needs for encryption, 3C now offers a library of encryption routines for the `C5x series 
of TI DSPs: the Encryption Package (EP). The EP contains a wide range of well known, well 
investigated symmetric encryption algorithms (e.g., DES, Triple-DES, IDEA©, SAFER). Its very 
attractive pricing scheme is based on the assumption, that no customer has use for all these 
algorithms at the same time. Usually he will evaluate some of the algorithms in question and then 
decide which one to use. The EP offers the unique possibility to do so: The customer only pays the 
price for one algorithm, he gets the whole library, he evaluates the routines and subsequently uses 
one of them. The EP is suited for integration in already `C5x-based products as well as for 
applications which need a flexible, standalone cryptographic module.

Company Background and Contact Information

In the beginning of 1994, two computer scientists, Toni Klingler and Michael Portz, founded the 3C 
Dr.Klingler, Dr.Portz GbR in Herzogenrath, Germany. The company is a spin-off of the nearby RWTH 
(Aachen University of Technology) one of Europe's best known research facilities in Engineering and 
Computer Science, with more than 36,000 students. Dr.Klingler and Dr.Portz worked for several years 
at RWTH on topics like communications technology, signal processing, parallel processing, computer 
networks, coding theory, data security, and cryptography. 3C is located in the Center of Technology 
Herzogenrath (TPH), the home of  more than 60 innovative companies, mainly working in the area of 
computer and communications technology.
Companies like Ericsson, Philips, Mitsubishi Semiconductor, ELSA, and Vobis, Europe's largest 
retail seller of computer and communications equipment, have their European research headquarters 
in the vicinity of the TPH.
