The National Institute of Information and Communications Technology (NICT) plans to establish the world’s first “data center impervious to data theft” by the end of fiscal year 2025. This initiative combines quantum communication technology with secret sharing technology to enable the protection of highly sensitive data for decades.
Key Points
1. Purpose and Technology
• Protect critical data such as medical and defense-related information from future risks posed by quantum computers.
• Utilize the quantum communication property of “quantum entanglement” to transmit encryption keys via photons, ensuring that any interception immediately alters the state of the photons, making the intrusion detectable.
• Combine this with secret sharing technology to make data indecipherable and distribute it across multiple locations.
2. Implementation Plan
• Collaborate with the University of Tokyo and Kyushu University to connect over 20 companies and universities within a 100-kilometer radius using dedicated lines.
• Validate performance using data from hospitals and financial institutions, aiming for practical implementation by the end of fiscal year 2025.
3. Applications
• Leverage medical data for drug discovery research.
• Safely manage asset information for financial institutions.
• Transfer technology to businesses and telecom carriers to promote commercialization.
4. Challenges and Future Outlook
• Cost reduction is a major challenge (e.g., maintenance of dedicated lines and devices).
• NICT aims to expand nationwide coverage by 2030 and establish international communication capabilities by 2035.
5. Background and Threats of Quantum Communication
• With advancements in quantum computing, current encryption methods are at risk of being deciphered in the future.
• Countries such as China and the EU are also developing quantum communication networks.
This project addresses threats to personal information and national security while advancing next-generation data center technology.
