BTQ Technologies Corp. has announced a strategic collaboration with Daou Data Corp. to strengthen Korea’s electronic payment systems against emerging quantum-era threats. The initiative focuses on deploying hardware-based post-quantum cryptography to secure critical financial infrastructure. The collaboration aims to enhance the security of Daou Data’s payment gateway (PG) and value-added network (VAN) systems by introducing hardware-rooted Korean post-quantum cryptography (K-PQC). This approach is designed to mitigate future risks such as “harvest now, decrypt later” attacks, where encrypted data captured today could be decrypted once quantum computing capabilities mature.
Under the agreement, BTQ will provide expertise in post-quantum security architecture, hardware-based trust frameworks, and deployment strategies for long-term institutional systems. Daou Data will explore implementation across its payment and enterprise platforms, with an initial focus on strengthening cryptographic key generation, processing, and management within secure hardware environments.
As part of the collaboration, Keypair will act as a supporting implementation partner, contributing hardware security modules and device-level integration. This builds on BTQ’s earlier investment in Keypair and its efforts to co-develop next-generation, post-quantum-ready security technologies for critical infrastructure.
Daou Data’s role is particularly significant given its position within Korea’s digital economy. As a central entity in the Daou Kiwoom Group, which includes major financial and IT affiliates such as Kiwoom Securities and Korea Information Certificate Authority (SignGATE), the company plays a key role in the country’s payment and digital identity ecosystem. This makes it a strategic partner for introducing quantum-resilient security into real-world financial systems.
The announcement also highlights BTQ’s growing presence in South Korea. Recent initiatives include a $15 million agreement with ICTK to develop quantum-secure chip technology, a proof-of-concept deployment with Danal for mobile billing and Paycoin services, and expanded work with Finger Inc. Group on banking solutions. These efforts collectively position BTQ across hardware security, payments, and financial infrastructure modernization in the region.
From a standards perspective, BTQ continues to align its technologies with global initiatives. Its QSSN framework has been approved as a global standards effort and is being positioned for submissions to major international bodies, including ITU, ISO, ETSI, and IEEE, supporting interoperability and long-term adoption of quantum-safe technologies.
Olivier Roussy Newton, CEO of BTQ Technologies, emphasized that quantum security is rapidly becoming a practical requirement for financial systems that must protect sensitive data over extended periods. He noted that the partnership with Daou Data represents a step toward deploying hardware-rooted security in real operational environments.
Sangjun Kim, CEO of Daou Data, added that the collaboration reflects a proactive approach to evolving cyber threats, ensuring that next-generation payment systems are designed to withstand both current and future cryptographic challenges.
Beyond payments, the companies expect the collaboration to open opportunities in broader enterprise security domains, including zero-trust architectures, secure logging, and hardware-based authentication. The initiative aligns with BTQ’s broader mission to help organizations transition toward quantum-resilient infrastructure by combining post-quantum cryptography, hardware security, and advanced validation frameworks.
