BISTRO: A Tool for Binary Component Extraction and Embedding

Summary

Researchers at Purdue University have developed BISTRO, a systematic approach to binary functional component extraction and embedding. BISTRO automatically performs the extraction of a functional component, with its instructions and data section entries non-contiguously located in the virtual address space, from an original binary program. This technology is also capable of embedding a binary component of any size and at any user-specified location in a target binary program without requiring symbolic information, relocation information, or compiler support. For both extraction and embedding, BISTRO preserves the functionalities of the target binary program and the extracted component by accurately patching them, using the same approach and technique. BISTRO performs extraction and embedding operations efficiently. After embedding, the "stretched" target binary program only incurs minor time and space overhead.

Technology Benefits

Does not require relocation information or special compiler supportWorks for both user-level programs and kernel-level programs Preserves the functionality of the target binary program and the extracted componentThe target binary incurs lower time and space overhead
