Abstract
A method of executing machine code using a microprocessor includes, for each datum D, computing a code Cusing a relationship C=Q(D)=P o F(D), where P is a predetermined function, Fis a function defined by the following relationship: F(D)=To . . . o To . . . o To T(D), and Tis αconditional transposition, configured by a secret parameter αr, that permutes two blocks Band Bof bits of the datum Don the basis of the value of the parameter αr. The method also includes computing a code Cusing the following relationship: C=C& C& . . . & C, where Cto Care the codes associated with data Dto Dcombined with one another by a Boolean operation D& D& . . . & Dwhere the '&' symbol designates the Boolean operation.
