양자컴퓨팅의 역습: 방산 보안의 패러다임 변화와 엑스게이트의 도전 > 뉴스

XGate is aiming for hegemony in the next-generation security market based on the solid profit structure it has built in its existing virtual private network (VPN) and firewall businesses. The company, which has already secured a significant share of the domestic public procurement market, presented a mid- to long-term vision to contribute to the advancement of the national defense system beyond providing simple solutions. CEO Joo Gap-su emphasized that aggressive investment in research and development (R&D) may be a burden on immediate profit margins, but it will be a key driving force that determines the company's survival in 5 or 10 years. In fact, Xgate completed a pilot project through close collaboration with a large defense company and achieved the result of demonstrating security technology optimized for tactical communication networks such as drones, unmanned aerial vehicles, and operational vehicles.

Xgate's core technology, the 'AX-Quantum' platform, is differentiated in that it is a hybrid method that combines an on-board quantum random number generator (QRNG) and quantum tolerant cryptography (PQC). This is the first in Korea to obtain National Cryptographic Module Verification (KCMVP) certification and is evaluated as having broken down institutional barriers to entering the public security market. Meanwhile, in academia, efforts are being made to reduce the weight of quantum cryptography technology, and the 'SQIsign' technology developed by Professor Lee Chang-min's team at Korea University has opened the way for quantum-resistant cryptography to be implemented even in Internet of Things (IoT) devices with limited memory. These technological advances are becoming an essential foundation for a complete redesign of security infrastructure in the defense and financial sectors.

The frontier of security is not limited to quantum cryptography but is also expanding into the area of ​​artificial intelligence (AI). If security threats in the past were simple password theft, modern attacks have evolved into advanced methods where AI finds vulnerabilities in the system's source code in real time. In order to respond to this, Xgate established an 'AI-to-AI' defense system and introduced AI-based anomaly detection and autonomous security equipment control functions. In particular, the natural language-based operating system utilizing the Large-Scale Language Model (LLM) allows non-experts to easily operate the defense system in fields where there is a shortage of security experts, and is evaluated as achieving both the versatility and efficiency of security.

The global discussion on quantum threats is spreading to the virtual asset market such as Bitcoin. Coinbase warned that the security transition of blockchain networks must be accelerated to prepare for the threat of quantum computers, and some experts pointed out that early Bitcoin addresses are at risk of being exposed to quantum attacks. However, venture capitalists such as Tim Draper countered that the first target of quantum computers would be banking systems that use more outdated security infrastructure than Bitcoin. Bitcoin has a hard fork technology that returns to a safe block through community consensus, but the fact that traditional financial institutions may be slow to respond due to the rigidity of the system is emerging as a key point of contention.
