ABSTRACT:
An electronic computation circuit comprises a multiplication operator with a serial input, a parallel input and a serial output, a first register connected by its output to the parallel input of the operator, a second register connected by its output to the serial input of the operator, a third register and a multiplexing circuit to selectively connect at least one data input terminal and the output of the operator to the inputs of the first, second and third registers, and to produce the output of the electronic multiplication circuit. Application to the operations of multiplication, squaring, exponentiation and modular inversion on a finite field denoted GF(2.sup.n).
