SYSTEM AND METHOD FOR OBSCURING BIT-WISE AND TWO'S COMPLEMENT INTEGER COMPUTATIONS IN SOFTWARE

Systems and methods related to concealing mathematical and logical operations in software. Mathematical and logical operations are disguised by replacing them with logically equivalent expressions. Each equivalent expression has at least two expression constants whose values are based on scaling and bias constants assigned to variables in the original mathematical or logical operation. Each of the expression constants may also be based on additive or multiplicative inverses modulo n of the scaling and bias constants. By replacing the original operations with more complex but logically equivalent expressions containing variables that also involve more operations, the true nature of the original operations is disguised.
