NTT Communications (NTT Com) has successfully conducted a demonstration experiment of encrypted communications that cannot be decrypted even by quantum computers in the entire system, including key supply, using quantum-resistant secure transport, a technological element of IOWN PETs that processes data while protecting privacy, and NTT Com’s patented technology.

In this demonstration, the company’s services were used to build multiple next-generation encryption technologies that cannot be decrypted even by quantum computers, and it was confirmed that safe web conferences can be realized on devices such as smartphones and tablets.

Quantum-resistant secure transport is an encryption communication technology that realizes safe communication even in the quantum computer era.

The key exchange function of quantum-resistant secure transport was installed on the company’s cloud system, and encryption key data was supplied to applications from the cloud system. NTT Com’s patented technology was used to realize a secure supply that would not be decrypted even when keys were supplied. For the application, the company’s development tool for video and voice calls, “SkyWay,” was used to build a web conference system incorporating these encryption technologies.
