Abstract
The invention concerns a method for encrypting, with a random quantity (r), a calculation using at least a modular operation (3), the method consisting in multiplying a first modulo (n) by said random quantity, in taking as modulo of the operation, the result (m) of said multiplication and in carrying out a modular reduction of the result of the operation, on the basis of the first modulo (n).
