Abstract :
At the University of Applied Sciences, Bremen, we have developed a Crypto-Chip for real-time enciphering connections in any ISDN-net in close cooperation with an ISDN-component manufacturer. The chip is called “TELECRYPT”, has less than 40 pads and is designed for the requirements of the telecommunication industry. Aside from the hardware implementation of the ciphering algorithm a new concept for the integration of a ciphering chip into telephones and telephone systems is proposed. The underlying technology can also be used for ciphering other serial datastreams. With the development of TELECRYPT it will be possible for the first time to set up telephones and telephone systems with minimum effort with one security module
