  • Device for security protection of digital data using elementary instructions data processing
    Patent number: 5412728
    Abstract: The calculator (MCA) is suitable for carrying out a non reversible and quasi-random operation with two operands on the incoming set of the said operation. The controller (MCO) breaks down the data sequence (SD) into a set of portions (Pro) which overlap and which form the first operand. The initial quantity (RO) and a first portion (PO) of the data sequence is loaded into the operand registers (01, 03). They then respond to each appearance of the calculated result (Rg) by loading the latter and another portion (P1) of the data sequence into the operand registers (01, 02), until said portions of the data sequence have been completely processed. The sequence of results supplies the outer data (DS).
