DeepSim: deep learning code functional similarity

2018

Measuring code similarity is fundamental for many software engineering tasks, e.g., code search, refactoring and reuse. However, most existing techniques focus on code syntactical similarity only, while measuring code functional similarity remains a challenging problem. …

Enhancing Randomization Entropy of x86-64 Code while Preserving Semantic Consistency

2020

Code randomization is considered as the basis of mitigation against code reuse attacks, fundamentally supporting some recent proposals such as execute-only memory (XOM) that aims at dynamic return-oriented programming (ROP) attacks. However, existing code randomization …

PYInfer: Deep Learning Semantic Type Inference for Python Variables

2021 · arXiv (Cornell University)

Python type inference is challenging in practice. Due to its dynamic properties and extensive dependencies on third-party libraries without type annotations, the performance of traditional static analysis techniques is limited. Although semantics in source code …
