Vulnerability Report: Entropy Threshold Risks in SSS Implementation

[Nyx38]

Summary

I have conducted a security analysis on Shamir Secret Sharing implementations and identified potential entropy leakages when using structured mnemonics.

Proof of Concept (PoC)

I have developed a specialized engine to demonstrate this vulnerability. You can review the mathematical model and the source code here:

Key Findings

• Lagrange Interpolation over GF256 allows for efficient share simulation.
• Deterministic validation via Zpub anchors significantly reduces brute-force complexity.

Looking forward to your feedback on these findings.
