Abstract: The disclosure concerns a method implemented by a processing device. The method includes performing a first execution by the processing device of a computing function based on one or more initial parameters stored in a first memory device. The execution of the computing function generates one or more modified values of at least one of the initial parameters, wherein during the first execution the one or more initial parameters are read from the first memory device and the one or more modified values are stored in a second memory device. The method also includes performing a second execution by the processing device of the computing function based on the one or more initial parameters stored in the first memory device.

Abstract: A method encrypts, using an encryption circuit, a first data value having a number n of first binary words, each word having a number m of bits. The encrypting includes generating a second data value having a same number n of second binary words of m bits each and outputting a result of the encryption. The number n is an integer greater than or equal to 3, m and n do not have a common integer division, and n or m is even. A second binary word of the second data value having a rank i is equal to a sum of: a first binary word having a same rank i; and a product of: a complement of a first binary word having rank ((i+1)modulo n), shifted by a first number of bit positions; and a first binary word having rank ((i+2)modulo n), shifted by a second number of bit positions.
