- TectumKeys uses physical entropy to create untraceable cryptographic keys
- The device blocks electromagnetic leaks and never exposes private keys externally
What happened: Tectum unveils quantum-safe key generator
Blockchain company Tectum has launched TectumKeys, a hardware cryptographic key generator designed to resist quantum threats. Unlike software-based solutions, the device uses physical entropy—a source of true randomness from natural physical processes—to generate private keys.
Veteran cryptographer Anatoly Klepov, with over 53 years of experience, led the development. His design, RNG 1.0, produces unrepeatable private keys and stores them entirely within the device. Since no data is transmitted or connected online, the system maintains complete air-gap security.

Why it’s important
Emerging quantum and AI technologies threaten to break current encryption. In response, TectumKeys offers a hardware solution built to withstand such risks. It supports use cases like cryptocurrency cold storage, secure authentication, and military communication.
Its aluminium alloy shell forms a Faraday cage to block electromagnetic interference. Inside, layered shielding with ferrite barriers and filters protects all components. These features make TectumKeys resilient to side-channel attacks—an increasingly common hacking method.
