Empowering Cybersecurity Through High Entropy

High Entropy Security specializes in securing cryptographic keys, distributed networks, and autonomous systems with enhanced cybersecurity infrastructure for defense, cryptocurrency, and IoT sectors, helping companies elevate their product offerings and end customers secure their assets.

Funded by the U.S. Department of Defense, HES’ patented technologies offer additional layers of protection with friendly-to-use and integrate cybersecurity schemes. To protect strategic information, HES’ Challenge-Response Pair (CRP) mechanisms generate error-free ephemeral keys from various templates (Physical Unclonable Functions, biometrics, sensors, images, digital files). HES also uses ternary computing and true random number generation for next-generation, quantum-resistant cybersecurity.

The Problem: Weak Entropy, Strong Adversaries

Today’s digital infrastructure faces escalating vulnerabilities—from IoT devices and sensors to mission-critical battlefield networks.

At the core of many cyber breaches is a single weakness: insufficient entropy in the security systems protecting networks, devices, and sensors.

Key Storage and Distribution

Modern systems still store cryptographic keys in devices, servers, or key vaults, with each serving as a potential point of compromise. Insider threats and side-channel analyses give attackers full control over the keys and encrypted data.

Signal Jamming and Network Noise

When networks rely on low-entropy, predictable protocols, just 25% corrupted data can break communication.
High-entropy key regeneration turns that noise into an advantage—maintaining secure links even in jammed environments.

Sensors in defense and aerospace are often vulnerable to fault injection or spoofing attacks, enabling adversaries to falsify readings without detecting tampering.
