Abstract

The invention relates to a method for encrypting or decrypting a sequence of successive data words in a data communications device, the method comprising executing an algorithm in which a sequence of quasi-random encryption words is generated from predetermined start values by performing operations in a finite group, and in which a respective one of the encryption words is combined with a respective one of the data words.
