EMBEDDING WATERMARK BASED ON MULTI-VARIABLE SIGNATURE ENCODING AT BEHAVIOUR LEVEL FOR REUSABLE IP CORE PROTECTION

摘要

Disclosed is an embedding watermark during high level synthesis at behavior level for reusable IP core protection. In one implementation, the present invention generates low cost watermarking solution during high level synthesis (HLS) based on multi- variable signature encoding for security of reusable IP cores. The watermark generated by the proposed approach satisfies the following properties: (a) low embedding cost (b) robustness (c) low watermark creation time (d) strong proof of authorship (e) lower hardware overhead (f) fault tolerance. Comparison with similar technique revealed the present invention obtains watermarked solution with lower embedding cost with lesser storage overhead and creation/embedding time.
