IDEMIA Secure Transactions Collaborates With KT in Advancing Post-Quantum Security For South Korea’s Defense Communications

Curated by Shubham · TechCapsules · Oct 26, 2026

AI-summarised brief · reviewed before publication

IDEMIA Secure Transactions partnered with South Korean operator KT to pilot SIM‑based post‑quantum cryptography (PQC) for defense communications under the 2026 PQC Pilot Conversion Project. The collaboration, led by the Ministry of Science and ICT and KISA, implements both NIST‑standardized and Korean PQC algorithms on a Quantum‑Resistant SIM platform, potentially delivering Korea’s first smart‑card running KpqC 1. The broader pilot will evaluate PQC across defense PCs, surveillance gear, drones, and 5G networks, demonstrating quantum‑safe key management in critical infrastructure.

💡 Why It Matters

· By embedding PQC into widely deployed SIM technology, the project offers a scalable, low‑overhead path to quantum resilience for national defense, setting a precedent for secure‑element adoption across government and critical sectors.

Arqit Invests in Sirius to Scale Tactical Edge Quantum-Safe Networking Following NATO…

Arqit Quantum Inc. announced a strategic investment in Sirius Computer, Inc., expanding a partnership that will embed Arqit’s Sovereign Key Platform and NetworkSecure adaptors into Sirius’s Crux software‑defined networking suite. The combined solution delivers symmetric, quantum‑safe encryption for COTS devices, tactical radios and UAVs without hardware changes, addressing the vulnerability of decentralized military communications over congested or untrusted radio links. The move follows Arqit’s selection as part of a NATO‑winning consortium to provide secure networking services. Sirius’s Crux platform, originally co‑created with the UK’s GCHQ, runs as a lightweight software layer on edge devices, bypassing the bandwidth limits of hardware‑based QKD and the latency of traditional post‑quantum algorithms. Arqit will fund engineering expansion in the US, UK and Germany and develop hardware acceleration for autonomous defense platforms, aligning with its shift toward defense alliances and key‑lifecycle management.

💡 By marrying software‑defined keys with existing tactical hardware, the alliance offers a deployable quantum‑safe shield for frontline forces, a capability previously limited to static, high‑bandwidth environments.

Starlink seems to be working normally again in Ukraine

SpaceX has reportedly lifted the restrictions it placed on Starshield, the military‑grade variant of its Starlink broadband service used by Ukraine’s armed forces. Defense Minister Evgeniy Khmara told reporters that the system is now operating normally, though the military continues testing and has not received an official explanation for the prior limitations. The restrictions, which lasted about ten days, caused Ukrainian drones traveling near 100 mph to lose connectivity, leading to loss of control of some unmanned aircraft and increased vulnerability of slower‑flying units. President Donald Trump called Elon Musk on Wednesday to request restoration of the service. Musk, who has publicly criticized President Volodymyr Zelensky, previously claimed Ukraine breached Starlink’s terms by employing the network for offensive drone strikes.

💡 Restoring Starshield averts an immediate collapse of Ukraine’s frontline communications, keeping its drone‑based warfare capability functional.

Nov. 5: Satellite Mission Management at the Edge

On November 5, SpaceNews and RTX will host a virtual event titled “Satellite Mission Management at the Edge,” focusing on the evolving demands of national‑security satellite operations. Speakers will examine how edge computing, automation, cloud‑native architectures, and modular design can speed technology upgrades, boost resilience, and lower costs while preserving security and control. The discussion will address the integration of emerging commercial capabilities with legacy systems and the need for faster decision‑making on orbit. The event, scheduled for 10:00‑10:45 a.m. ET via Zoom, will be recorded for later viewing. RTX, a defense and aerospace firm with over 180,000 employees and projected 2025 sales exceeding $88 billion, will showcase its role in modernizing mission management for defense and intelligence customers.

💡 Edge‑focused technologies promise to shrink the latency between threat detection and satellite response, giving U.S. defense assets a decisive operational edge.

After Starshield interruption, Ukraine wants to build its own satellite communication network…

Ukraine’s military signed a letter of intent with Finnish telecom giant Nokia and satellite‑imaging firm ICEYE to explore a sovereign satellite‑communication network. The move follows a reported throttling of Starshield, the U.S.-government‑controlled, jamming‑resistant version of SpaceX’s Starlink, which limited drone bandwidth on Oct. 14 and forced several UAVs to crash. Kyiv, which relies on Starlink and Starshield for command, control and intelligence, lacks ownership of any orbital assets. ICEYE, which already supplies synthetic‑aperture‑radar imagery to Ukrainian forces, and Nokia, which announced a broader partnership to help nations build independent satcom systems, will assess trusted, high‑performance connectivity that Ukraine can control. The initiative aims to reduce dependence on foreign constellations amid ongoing Russian aggression and strengthen its strategic communications resilience significantly.

💡 Reliance on externally controlled constellations leaves Ukraine vulnerable to political or technical restrictions, a risk now exposed by the Starshield slowdown.

Russian APT28 Breaches NATO Naval Shipbuilder in NATO Country, Deploys New Reflective…

A Russia‑linked state‑sponsored group identified as APT28 (also known as BlueDelta, Fancy Bear and Forest Blizzard) has been linked to cyber‑espionage attacks against two NATO member states. The Symantec Threat Hunter Team, tracking the activity under the name Swallowtail, reported the use of a backdoor called HOOKEDGE and a previously undocumented reflective loader named ld.exe. Victims included a law‑enforcement agency, a naval shipbuilder and a military‑aircraft‑engine manufacturer. In the shipbuilder breach, attackers returned to the compromised host for a week, stole credentials via two distinct methods, opened a persistent SSH tunnel and deployed the new loader, which decrypts and runs an encrypted payload in memory using a runtime key. The campaign shifted from webhook‑based command‑and‑control to a dedicated IP address for tasking and exfiltration. The most recent indicator was a Visual Basic Script launcher observed on 24 September 2026; the extent of data exfiltration remains unknown.

💡 The operation demonstrates APT28’s evolving toolset and persistence tactics, raising the risk profile for critical defense suppliers within NATO.

Arqit Invests in Sirius to Develop Quantum-Safe Defence Communications

Arqit Quantum Inc. has invested strategically in Sirius Computer to accelerate the development of Crux, a software‑based quantum‑safe communications platform. The partnership merges Sirius’s secure networking hardware with Arqit’s Sovereign Key Platform and NetworkSecure adaptors, enabling secure data exchange across mobile devices, cloud, and autonomous systems. The investment will fund product development, integration, and joint go‑to‑market efforts targeting NATO members, the UK Ministry of Defence, and the US Department of Defense. Both companies aim to expand secure networking solutions without replacing existing infrastructure.

💡 The collaboration promises a scalable, lightweight quantum‑safe solution that can be deployed on commercial devices, reducing the logistical burden on defence forces while ensuring long‑term data protection.
