Toppan and ISARA Partner to Develop Post-Quantum Public Key Cryptography on Smart Cards

Tokyo – April 6, 2021 – Toppan Printing (Toppan) (TYO: 7911), a global leader in communication, security, packaging, décor materials, and electronics solutions, and ISARA Corporation (ISARA), are launching a partnership for the joint development of smart cards equipped with post-quantum public key cryptography.

The public key cryptosystems widely used today will be vulnerable to attacks from large-scale quantum computers, which are expected to come into practical use around 2030. Toppan and ISARA aim to equip smart cards with public key cryptosystems that are secure against attacks from quantum computers to ensure secure verification of access authentication. In collaboration with Japan’s National Institute of Information and Communications Technology (NICT), further assessment is planned of the feasibility of smart cards equipped with post-quantum public key cryptography on H-LINCOS,1 a testbed of quantum secure cloud technology.2 These activities aim to promote the use of quantum secure cloud technology and to provide services and solutions for secure backup and communication of highly sensitive digital information.

Existing smart cards versus smart cards with post-quantum public key cryptography

Background

As the digital society accelerates, smart cards, which are used for various access authentication applications, are growing in importance. Smart cards are equipped with public key cryptosystems such as RSA for authentication, but with the anticipated practical application of quantum computing technology within the next 10 years, there is a risk that existing public key cryptography could be decrypted. This has given rise to a need for public key cryptosystems that are secure against quantum computing attacks.

Details of the collaboration

Toppan and ISARA are leveraging expertise in smart card security and authentication technology in a pioneering attempt to equip smart cards with post-quantum public key cryptography. Access authentication using such smart cards is a groundbreaking technology with the potential to revolutionize economies and societies around the world. Early development and rollout will contribute to creating and maintaining infrastructure for safe and secure information communication. Success in establishing the technology will have a significant impact on every environment in which smart cards are used, helping to ensure secure access authentication and enhancing security for society in the future.

Specifically, the project aims to develop a program for smart cards to implement post-quantum algorithms that generate and verify digital signatures and to verify the functionality and applicability to smart cards. Toppan and ISARA will also investigate the feasibility of adapting this smart card technology for use in quantum secure cloud technology. The two companies intend to begin the integration of post-quantum public key cryptography into smart cards and perform the technical verification of authentication systems in 2022, targeting limited practical application in 2025 and the launch of services in 2030.

Roles of each organization

Toppan

Through the development and manufacture of smart cards, Toppan has accumulated a range of smart card security technologies, including encryption, authentication, and unauthorized access prevention. Leveraging this expertise, Toppan will work to contribute to the establishment of a safe and secure society in the age of quantum computing through support for the application of post-quantum public key cryptography to smart cards and the expanded use of quantum secure cloud technology, as well as the provision of services and solutions such as secure backup and data distribution for highly sensitive information. Through joint development with ISARA, Toppan hopes to equip smart cards with post-quantum public key cryptography and introduce smart card-based access authentication to quantum secure cloud technology.
