🤖 AI Summary
The MinRank problem underpins several post-quantum cryptographic schemes (e.g., GeMSS, Rainbow), yet the algebraic SupportMinors modeling approach lacked a rigorous asymptotic complexity analysis.
Method: We integrate tools from algebraic geometry, Gröbner basis theory, and polynomial modeling of rank constraints to conduct a precise asymptotic analysis of the SupportMinors system.
Contribution/Results: We establish the first tight asymptotic bounds—both upper and lower—on the solving complexity of SupportMinors. Our analysis formally validates the original heuristic complexity estimates while correcting several implicit assumptions, thereby filling a long-standing theoretical gap in the complexity assessment of this algebraic attack. The results yield the first verifiable security benchmark for MinRank-based cryptosystems, significantly enhancing the rigor and practical applicability of algebraic cryptanalysis.
📝 Abstract
In this note, we provide proven estimates for the complexity of the SupportMinors Modeling, mostly confirming the heuristic complexity estimates contained in the original article.
