Decent Cybersecurity of Slovakia has introduced a range of quantum-resistant Application-Specific Integrated Circuits (ASICs) at the Defence and Security Equipment International (DSEI) Japan 2025, which took place in Chiba on May 21-23.
It is a big step forward in protecting digital infrastructure from the threat of quantum computing—all from a new class of material.
It was really cool to see our next door neighbours, a Slovakian company named Decent Cybersecurity, with the only other stand at the event offering any solution in the form of three leading post-quantum cryptography technologies: SpaceShield STM for satellite communications, DroneCrypt UTM for UAV security and QPP (QuantumProof Protocol) for use-cases covering a wide range of functions.
These are specifically designed to be resistant to the increased computational capabilities of future quantum computers.
The company is also considering joining forces with Rapidus, a Japanese-based corporation, to form a place for the production of the world’s initial 2nm post-quantum ASIC microchips in Japan.
The pairing of Decent Cybersecurity’s expertise in post-quantum cryptographic techniques with Rapidus’s advanced semiconductor fabrication will usher in a new era of hardware-based quantum resistant security. The Japanese government is backing Rapidus with important subsidies in order to reinforce the production of next-generation semiconductors.
Decent Cybersecurity had excellent visibility at DSEI Japan, with key industry and government professionals from Japan’s defense, aerospace and government institutions. “A frequent critical mistake of Western commercial and state parties is to assume that they can come to East Asia to provide security expertise and leave the region once their work is finished,” says company CEO Matej Michalko, “It doesn’t work that way in East Asia.”
Conjuring memories of the infamous so-called “sprinter model” under which European motorcycle exports were popular in East Asia during the fifties, ADH will instead concentrate on establishing a long term trusted security relationship in the East Asian defense ecosystem, and is actively considering a permanent office in Japan to better serve local clients.
H.E. Ivan Surkoš, the Slovakian Ambassador of Japan, stopped at the Decent Cybersecurity booth to show that his country was in support for the strategic advancement of the company and the innovation of digital security in Slovakia.
It is a timely announcement given that, as part of his keynote address, “The Role of Global Tech in Regional Security,” at the conference, Shigeru Ishiba, the Japanese Prime Minister, highlighted the importance of international technology collaboration for regional security.
The team of Decent Cybersecurity has “Secret” level security clearances with NATO, the EU, and different the national authorities, this kind of trustworthiness adds to their novelty solutions. “DSEI Japan is an excellent opportunity for OSINT to showcase its offerings to Japan – a country that will have to raise its cybersecurity shield in the light of the advancing power of the quantum era.
