Common Program Similarity Metric Method for Anti-Obfuscation

Protecting Genomic Privacy by a Sequence-Similarity Based Obfuscation Method

In the post-genomic era, large-scale personal DNA sequences are produced and collected for genetic medical diagnoses and new drug discovery, which, however, simultaneously poses serious challenges to the protection of personal genomic privacy. Existing genomic privacy-protection methods are either time-consuming or with low accuracy. To tackle these problems, this paper proposes a sequence simi...

Incremental Program Obfuscation

Recent advances in program obfuscation suggest that it is possible to create software that can provably safeguard secret information. However, software systems usually contain large executable code that is updated multiple times and sometimes very frequently. Freshly obfuscating the program for every small update will lead to a considerable efficiency loss. Thus, an extremely desirable property...

Cryptographic Program Obfuscation

Implementing Cryptographic Program Obfuscation

Program obfuscation is the process of making a program “unintelligible” without changing the program’s underlying input/output behavior. Although there is a long line of work on heuristic techniques for obfuscation, such approaches do not provide any cryptographic guarantee on their effectiveness. A recent result by Garg et al. (FOCS 2013), however, shows that cryptographic program obfuscation ...

Studies in Program Obfuscation

Program obfuscation is the software analog to the problem of tamper-proofing hardware. The goal of program obfuscation is to construct a compiler, called an “obfuscator,” that garbles the code of a computer program while maintaining its functionality. Commercial products exist to perform this procedure, but they do not provide a rigorous security guarantee. Over the past decade, program obfusca...
