Abstract

The method for parallel keyed randomizing consists in supplying information data in the form of sequence. The information data randomizing is carried out by means of rasing to the power by information data modulo according to iterative rule by a prime great number modulo carrying out for result of addition by means of the third adding device of data block values, the address being calculated in parallel as a result of adding confidential data and a counter value by means of the first adding device and adding a confidential data and a counter value of the second adding device. The keyed data supplements with confidential data. The confidential data is given in the form of sequence. The sum of information sequence elements is parted. Each part is rased to a power which is received by adding a key sequence element and the sum of results of rasing to the power received on the previous step, by a prime number modulo. The modulo rasing to the power of each part of the sum of information sequence elements is carried out in parallel the degree to be rased of the information sequence elements is received by means of adding results of rasing to the power received on the previous step of modulo rasing units.
