System and Method for blocking to protect behaviors mediated by software program and device

摘要

A method for re resistant to Reverse Engineering Software. Replace at least a First Constant (Mathematical expression, etc.In an expression of a Second processing with Mixed boolean and Mathematical expression for the bit level, constant expression is simpler than the second, and the second expression is based on the Value or the variables found in the first Constant (or expression).The Evaluation of the second Mixed boolean and Mathematical expression level Card produces a value that preserves the value of the constant: First, both with the original value of the first Constant or the original value of the First Expression.In which case the second Mixed boolean and Mathematical expression of bit level are obtained from the first Constant to convert the first Constant Mathematical identities; or, in coded form, as a new value, which can be converted back into the original value of the Prim It was constanteal apply a function Preserving decoding InformationIn which case the second Mixed boolean and Mathematical expression level obtained from the first bit Constant by changing the first conversion Constant by a combination of Mathematics with identities and Transformation according to a Coding function that preserves the Information.
