Interpretation Mila Dalla Preda and Roberto Giacobazzi Dipartimento di Informatica, Università di Verona Strada Le Grazie 15, 37134 Verona (Italy) [email protected] | [email protected] Abstract. In this paper we introduce a semantic-based approach for code obfuscation. The aim of code obfuscation is to prevent malicious users to disclose properties of the original source program. ...

Program obfuscation is a widely employed approach for software intellectual property protection. However, general obfuscation methods (e.g., lexical obfuscation, control obfuscation) implemented in mainstream obfuscation tools are heuristic and have little security guarantee. Recently in 2013, Garg et al. have achieved a breakthrough in secure program obfuscation with a graded encoding mechanis...

Obfuscation is gaining momentum as a protection mechanism for the intellectual property contained within or encapsulated by software. Usually, one of the following three directions is followed: source code obfuscation is achieved through source code transformations, Java bytecode obfuscation through transformations on the bytecode, and binary obfuscation through binary rewriting. In this paper,...

In recent years code obfuscation has attracted research interest as a promising technique for protecting secret properties of programs. The basic idea of code obfuscation is to transform programs in order to hide their sensitive information while preserving their functionality. One of the major drawbacks of code obfuscation is the lack of a rigorous theoretical framework that makes it difficult...

• We investigate how consumers’ incentives to comparison shop within a firm affect price competition in multiproduct oligopolies. A new search model with deadlines and random results is presented. find that firms benefit from offering discount on subset of their products, which amplifies for intrafirm shopping alleviates competition. This set pricing (i) engages consumers comparing products ins...
