Webtechniques are suﬃcient to bypass most commercial and open source malware detection techniques, rendering the lack of de-obfuscation fea-tures in tools a vulnerability. This paper focuses on a speciﬁc obfuscation technique, which we call XOR(255). XOR is the exclusive-or binary operation. XOR binary op-erations are performed with “keys.” WebOur results build on a simple and powerful combination of techniques that were introduced in previous works in several contexts. In particular, our garbling scheme is based on a natural generalization of the Free-XOR technique of Kolesnikov & Schneider [KS08], allowing for free addition mod larger m, rather than just mod 2.

WebThis paper will obtain similar (but slightly different) results by using the "standard H technique" instead of the “Hσ technique”, and it will be interesting to compare the two techniques, their similarities and the differences between the proofs and the results.
