Building on our prior work that introduced multi-vantage-point domain validation (multiVA) and evaluated its real-world deployment at Let's Encrypt, this paper takes the next step by rigorously quantifying its security under real-world routing conditions, identifying remaining attack surfaces, and exploring how to further strengthen multiVA resilience through strategic deployment adjustments.
