Abstract: This invention describes the use of the features of modern reconfigurable and self-reconfigurable VLSI technology to design highly secure unknown and secret physical functions for security applications. Several examples of sample implementation scenarios for self-generated secret hard-wired cipher- and/or hash functions architectures are shown. A designed, true-random, electronic mutation process autonomously activates the creation of such secret unknown functions in a self-reconfiguring VLSI architecture. It is also shown that such mutation processes can be designed to evolve dynamically in a non-predictive manner to come up with highly secure physical security mechanisms and protocols. This self-evolving property of such functions offers a great security quality which can enhance the security and identification resilience of electronic units to levels similar to those only available in biological systems with highly accurate DNA identification and secured history tracing of living entities.

Abstract: A method of encrypting data, a telecommunications terminal and an access authorization card are described, which permit utilization of services of one or more service providers independently of a network operator or manufacturer of the telecommunications terminal. Encrypted data is transmitted between a service provider and the telecommunications terminal over a telecommunications network. Data to be transmitted over the telecommunications network is encrypted as a function of the service provider selected.

Abstract: In a method and apparatus for encoding or decoding data, a fire code is used for this with a polynomial G(x)=P(x)(1+xC), wherein the value for C can be variably selected, and in addition, the error correction and detection properties of the redundancy integrated into the decoding apparatus can be set independently of the encoding device, and these properties depend solely on the number of redundancy bits used.
