Abstract

A computing device configured to check a software key of a user terminal device. The computing device includes: an ALU, a plurality of registers having a storage capacity of at least x bits, and a data memory. The computing device is configured to perform a multiplication of two y-bit numbers each formed by a plurality of x-bit digits, as follows: loading the x-bit digits of the y-bit numbers into the registers, and repeatedly calculating, using the ALU, for all x-bit digits of the result of the multiplication of the y-bit numbers, an x-bit digit of the result based on those registers that store the associated x-bit digits of the y-bit numbers, and storing the calculated x-bit digit of the result in the data memory. Y is an integer multiple of x.
