摘要： A method for rendering software resistant to reverse engineering. Replace at least one first constant (mathematical expression, etc.) in a computational expression with a second mixed mathematical and bitwise-Boolean expression, the first constant being simpler than the second expression and the second expression being based on the value or the variables found in the first constant (or expression). Evaluation of the second mixed mathematical and bitwise-Boolean expression produces a value preserving the value of the first constant, either: with the original value of the first constant or the original value of the result of the first expression, in which case the second mixed mathematical and bitwise-Boolean expression is obtained from the first constant by converting the first constant by mathematical identities; or, in an encoded form, as a new value, which can be converted back to the original value of the first constant by applying an information-preserving decoding function, in which case the second mixed mathematical and bitwise-Boolean expression is obtained from the first constant by modifying the first constant by a combination of conversion according to mathematical identities and transformation according to an information preserving encoding function.

一种渲染软件抵抗逆向工程的方法。用计算表达式中的第二个混合数学和位布尔表达式替换至少一个第一个常量（数学表达式等），第一个常量比第二个表达式更简单，第二个表达式基于值或找到的变量在第一个常量（或表达式）中。对第二个混合数学和位平面布尔表达式的评估会产生一个保留第一个常量值的值：用第一个常量的原始值或第一个表达式的结果的原始值，在这种情况下，第二个混合数学和按位布尔表达式是通过用数学身份转换第一个常数从第一个常量中获得的; 或者以编码形式作为新值，通过应用信息保持解码函数可以将其转换回第一常数的原始值，在这种情况下，第二混合数学和比特布尔表达式从首先通过根据数学身份进行转换和根据信息保持编码功能进行转换的组合来修改第一常数，这是第一常数。
