We address the practicality challenges of secure program obfuscation by implementing, optimizing, and experimentally assessing an approach to securely obfuscate conjunction programs proposed in [1]. Conjunction programs evaluate functions f (x1, . . . , xL) = ∧ i∈I yi, where yi is either xi or ¬xi and I ⊆ [L], and can be used as classifiers. Our obfuscation approach satisfies distributional Vir...

Code obfuscation is a promising defense technology that secures software in a way that makes the cost of reverse engineering prohibitively high. While there are a number of commercial obfuscation tools on the market, there is no standard measurement to analyze and evaluate their strength. This paper addresses this challenge. An analytical metrics is developed to quantify the performance of obfu...

In this paper we investigate variation in the translation of three vague quantifiers, many, some and a few between English and Chinese. Studies of ‘linguistic vagueness’ (sometimes called ‘language vagueness’ in previous research) regard vagueness as a general phenomenon in language. In this type of study, vagueness is often discussed – but not limited – to indeterminacy of the referential boun...
