The Internet has become indispensable for modern society, and all kinds of information are exchanged over the internet. However, this relies on the premise that the security of the Internet is guaranteed.. It is said that in the near future, if general-purpose quantum computers are put into practical use, there is a risk that the currently safe encryption protocols may be decrypted. It is no exaggeration to say that society as a whole will be affected if the security of the Internet becomes compromised.
At the Research Institute of Advanced Technology, we are working on the research and development of post-quantum computer cryptography technologies including PQC (Post-Quantum Cryptography) and QKD (Quantum Key Distribution) in preparation for the era when general-purpose quantum computers are put into practical use. Furthermore, we have partnered with Sandbox AQ, a software company based in the United States that utilizes quantum technology, and are jointly demonstrating the verifications of PQC for practical applications such as VPN.
The development and adoption of post-quantum cryptography technology will make it possible to securely use the Internet even in the era when general-purpose quantum computers are put into practical use. For example, banks and credit card companies can safely protect user information and transaction data. The same applies to government agencies and medical institutions that handle personal and confidential information, allowing all users to enjoy these services without any security concerns.
