Web13 sep. 2024 · Mixed-Boolean Arithmetic We can also observe in Figure 2 that the function uses an MBA as an opaque zero or more precisely an opaque boolean. Generally speaking, MBA are widely used by the obfuscator but they are usually represented under their simple form like (A \oplus B) + (A \& B) \times 2 (A ⊕ B) + (A&B) × 2 . Web8 aug. 2024 · Mixed-Boolean-Arithmetic Obfuscation is a technique which represents an expression to be concealed in a semantically equivalent, but syntactically more complex form. For example, the expression x + y, can be rewritten as (x ^ y) + 2 * (x & y), effectively making its behaviour harder to comprehend.
