Blockchain company Tectum has officially launched TectumKeys — a hardware-based cryptographic key generator built to deliver quantum-level security, eliminate traditional software vulnerabilities, and protect against electromagnetic interception through physical isolation.
At the core of TectumKeys is a physical entropy generator, RNG 1.0, developed by a team of cryptographers led by Anatoly Klepov. TectumKeys was fully designed by Klepov, who has more than 53 years of experience in cybersecurity and hardware encryption. Its architecture adheres to the TEMPEST-grade standards used by defence industries, central banks, and critical infrastructure providers.
TectumKeys relies on true unpredictability – physical entropy. Physical entropy sources are cutting-edge technologies that generate true random numbers by harnessing the inherent unpredictability of physical phenomena.
Unlike conventional methods that rely on deterministic algorithms, physical entropy is based on physical processes that are fundamentally impossible to predict, even with full knowledge of the system. Two noise diodes are fused together within TectumKeys to produce true random numbers, ensuring every private key is mathematically untraceable. The result is ultra-secure, non-repeating private keys generated and stored entirely on-device, never exposed externally or transmitted, preserving air-gap security.
The device is enclosed in a CNC-machined three-millimetre aluminum alloy casing with internal shielding that forms a Faraday cage. Partitioned metal walls, ferrite barriers, and LC filters isolate all functional blocks, effectively suppressing signal leakage and blocking electromagnetic side-channel attacks.
TectumKeys integrates with systems via a USB with a proprietary encrypted protocol, enabling seamless interaction with Tectum’s Key Generation Center software via protected channels. It meets electromagnetic compliance criteria (emissions are less than or equal to two µV/m at one metre), aligned with the TTA (TEMPEST Test Approach) standard.
By leveraging quantum entropy, air-gapped storage, and physically shielded hardware, TectumKeys offers a solution for wallet key generation, cold storage, government communications, and high-security authentication systems, particularly in an era of AI-driven and quantum threats.
“Mathematics alone can’t protect against physical compromise — that’s why TectumKeys is built from physics up,” said Klepov. “In a world where advanced computing threatens conventional encryption, we must evolve beyond software-based defences.”
