A detection framework for semantic code clones and obfuscated code

Expert Systems with Applications, 2018
Abstract Code obfuscation is a staple tool in malware creation where code fragments are altered substantially to make them appear different from the original, while keeping the semantics unaffected. A majority of the obfuscated code detection methods use program structure as a signature for detection of unknown codes.

Semantic Code Clones in Logic Programs

2013
In this paper, we study what is a semantic code clone pair in a logic program. Unlike our earlier work, that focused on simple syntactic equivalence for defining clones, we propose a more general approximation based on operational semantics and transformation rules.

Semantic-Based Code Obfuscation by Abstract Interpretation

Journal of Computer Security, 2005
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.

Image semantic coding using OTB

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Semantic coding is used to provide image representation able to make semantics emerge and to learn it. This process is based on a basic decomposition of the image content into ”vi-sual words”; using spatial relationships, these visual words are aggregated to form structures and (inter)active learning is used to associate semantics to the emerging ...

Semantic compaction, transmission, and compression codes

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
In Bell Syst. Tech. J., 1948, Shannon wrote: "The semantic aspects of communication are irrelevant to the engineering problem." Indeed Shannon demonstrated that the information that is generated by a source depends only on the statistics of the source, and not on the meaning of the source output.

The Physical Semantics of Code

2019
Numerous mishaps involving cyber-physical systems have occurred due to divergences between software representations of the physical world and the actual phenomena be- ing represented. An example is the failure of the Mars Polar Orbiter mission due to the fact that a physical impulse was calculated in two different unit systems: impe- rial and metric[1].

The semantic code today

American Documentation, 1962
AbstractA sampling of the file of encoded abstracts of technical articles produced for the information retrieval system in operation at the Center for Documentation and Communication Research at Western Reserve University has been analyzed for the incidence of terms which had not yet appeared in the semantic code dictionary.
