Secure and efficient cryptography technology for the post-quantum eraPost-Quantum Cryptography TechnologyNTT Social Informatics Laboratories

We are researching and developing the next-generation cryptography technology necessary to eliminate the security issues of eavesdropping, tampering and impersonation in the post-quantum era. By applying next-generation cryptography technology to systems and applications that require a high level of security, we aim to achieve a safe and secure ICT foundation.

The development of a quantum computer that can calculate faster even than a supercomputer is currently underway, with practical development expected by 2030.
Quantum computers are expected to be used in various fields such as medicine and finance. However, from a security perspective, there is concern that existing cryptography will be compromised (i.e. decoded) because it will become possible to solve mathematical computational problems (such as integer factoring), the basis for existing encryption security, in a reasonably short time. The challenge is researching and developing encryption technology that is both secure and efficient to create services that utilize post-quantum cryptography, the security of which is based in mathematical computing problems that cannot be solved even by quantum computers.

• The development of cryptography technology that prevents eavesdropping, tampering, or impersonation even with a quantum computer
• The NTRU encryption/key-exchange technology, which uses NTT technology, was selected as a finalist for standardization by the US National Institute of Standards and Technology (NIST)
• Development of a more secure and efficient signature technology than finalists of the NIST standardization competition.

• Applications such as secure communication and authentication infrastructure using post-quantum cryptography
• Replacing existing cryptography applications with post-quantum cryptography
