Toppan and NICT Enter Agreement for Joint Research on Post-Quantum Public Key Cryptography

(WhatTheyThink) Toppan Printing (Toppan), a global leader in communication, security, packaging, décor materials, and electronics solutions, and Japan’s National Institute of Information and Communications Technology (NICT) have entered into an agreement to conduct joint research on bringing post-quantum public key cryptography to quantum secure cloud technology.
Quantum secure cloud technology fuses quantum cryptography and secret sharing technologies to facilitate secure data communication, storage, and use. The establishment of the technology will not only ensure a high level of security that makes tampering and decryption impossible, but also enable the collection, analysis, processing, and use of highly sensitive personal and corporate information accumulated in such fields as medical care, new materials, manufacturing, and finance.
Targeting expanded use of quantum secure cloud technology, Toppan and the NICT will bring together their respective technologies, insight, and experience to drive the application of post-quantum public key cryptography in wider society based on access authentication using smart cards equipped with such cryptosystems. The project will focus on secure data communication, storage, and use enabled by introducing this kind of access authentication to the Healthcare Long-term INtegrity and Confidentiality protection System (H-LINCOS)1 developed by the NICT and its collaborative partners.
