What was the purpose of this proof-of-concept experiment?

The purpose was to verify the technical feasibility of introducing Post-Quantum Cryptography (PQC) technology to enhance the security of internet communications in Daiwa Securities' online services, in preparation for the potential loss of security in conventional public-key cryptography due to the advent of quantum computers.

What were the findings of the proof-of-concept experiment?

It was found that while the increase in processing time associated with PQC key exchange was limited, the communication volume and packet count increased due to larger key sizes. Therefore, prior confirmation is necessary for communication environments where sufficient bandwidth is not secured.

What challenges and countermeasures are considered for PQC adoption?

To address the increase in communication volume due to larger key sizes, prior confirmation of the communication environment is necessary. Furthermore, phased migration based on industry standardization trends, establishing a system-wide cryptographic migration framework, and creating an inventory of cryptographic usage and algorithms are considered effective.

Which companies participated in this proof-of-concept experiment and what were their roles?

Participants included Daiwa Securities Group Inc. (coordination, policy formulation), Daiwa Securities (compatibility, performance, operational impact verification), Daiwa Institute of Research (verification environment construction, scenario creation, technical verification, evaluation, white paper creation), NEC (providing expert PQC opinions, enhancing technical reliability, white paper review), F5 Networks Japan (providing PQC-compatible ADCs), and DigiCert Japan (providing insights on international standardization trends and PKI expertise).

PQC (Post-Quantum Cryptography) is a general term for cryptography that is considered to maintain security even when quantum computers with sufficient computing power become practical.
