Formally Verifying Undetectability in Hidden Communication Systems with Maude-HCS

Submitted by Katie Dey on

ABSTRACT

A hidden communication system (HCS) embeds hidden messages within ordinary network activity by repurposing existing protocols as subliminal channels. Although prior work provides useful tools for assessing the detectability of the HCS, there is no general and modular framework that both formalizes what it means for an HCS to be undetectable and formally verifies that a concrete implementation satisfies this property.

ABSTRACT

In this talk I will describe HOARDE — the Hierarchical Orchestration of Autonomous Rigorous Digital Entities — built by my company, Sigil Logic, since our founding in September, 2025. HOARDE realizes what we call the NINJA methodology (Non-Intrusive Judicious Assurance): rigorous engineering with applied formal methods, made accessible to every engineering team through AI agents.

ABSTRACT

2025 Best Scientific Cybersecurity Paper Competition Winner: zkPi: Proving Lean Theorems in Zero-Knowledge

Submitted by Katie Dey on

The National Security Agency (NSA) awarded the 13th Annual Best Scientific Cybersecurity Paper Competition to “zkPi: Proving Lean Theorems in Zero-Knowledge". The winning paper, authored by Evan Laufer, Alex Ozdemir and Dan Boneh of Stanford University, proposes a groundbreaking method to use Zero-Knowledge Proofs to secure Lean Theorems. This is a method to protect the potentially sensitive information that is contained within lean theorems especially when used to verify system properties.
