BTQ Technologies Corp. (NASDAQ: BTQ) announced a strategic collaboration with Daou Data Corp. to develop hardware-rooted post-quantum security for Korea's electronic payment systems. The partnership focuses on strengthening payment gateway and value-added network infrastructure through Korean post-quantum cryptography.

The collaboration combines BTQ's post-quantum cryptography expertise with Daou Data's enterprise IT and payment infrastructure operations. Daou Data serves as the de facto holding company of the Daou Kiwoom Group, which includes seven listed affiliates across KOSPI and KOSDAQ operating in finance, IT, security, HR, content, and commerce sectors.

Keypair will support implementation of the initiative, building on BTQ's previously announced strategic investment and co-development relationship with the company. The partnership aims to establish secure architecture for key generation, cryptographic processing, and key management within dedicated hardware boundaries for payment systems.

The initiative addresses emerging risks from quantum computing, including "Harvest Now, Decrypt Later" attacks, where encrypted data intercepted today could be stored and decrypted once quantum systems become sufficiently powerful.

"Quantum security is no longer a theoretical issue reserved for the lab. It is becoming an operational requirement for real financial infrastructure," said Olivier Roussy Newton, CEO of BTQ Technologies.

Sangjun Kim, CEO of Daou Data, stated that the partnership represents "a forward-looking approach to payment security and helping shape the next standard for secure, quantum-resilient financial infrastructure."

BTQ has expanded its Korea operations through recent partnerships, including a $15 million agreement with ICTK for quantum-secure chip technology development and collaborations with Danal, Korea's mobile carrier billing provider, and Finger Inc. Group, described as Korea's largest banking-solutions developer.

The collaboration information was disclosed in a company press release statement.
