Encryption of digitised information

摘要

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.
