Encryption of digitised information
TLDR
In this paper, a method for delay-free encryption of digitised, unencrypted or pre-encrypted information using retrieval information (800) provided by a higher-order arrangement or derived from the un-encrypted or pretax information (700), one encryption function value in each case being retrieved, synchronously with the retrieval information and for the purposes of encryption by an encryption function (900), from a pre-defined quantum (600) of encryption function values which are genuinely random in terms of the autocorrelation function.Abstract:
The invention relates to a method for delay-free encryption (900) of digitised, un-encrypted or pre-encrypted information (700) using retrieval information (800) provided by a higher-order arrangement or derived from the un-encrypted or pre-encrypted information (700), one encryption function value in each case being retrieved, synchronously with the retrieval information (800) and for the purposes of encryption by an encryption function (900), from a pre-defined quantum (600) of encryption function values which are genuinely random in terms of the autocorrelation function. The decryption of encrypted information (700, 1000) is described by the same method.read more

Pseudo-random noise series generator
TL;DR: In this paper, a pseudo-random noise series generator which can change the timing of generation of a PN series arbitrarily and with no instantaneous cut-off of the output is presented. But this generator is not suitable for the address generator.

Variant key matrix cipher system
TL;DR: In this article, a product cipher is used to encode a stream of binary data by using a modulo-two addition function, which is dependent on previous internal cipher digits transmitted and varies for each message bit processed.
