Last, let's look at trends in the standardization of device security.
Device security standards cover security requirements related to device security and methods for evaluating implemented devices to check that they meet these requirements. The standards form the foundation of design and implementation requirements for the vendors that manufacture the devices. They are also used as procurement standards by companies that use the devices to supply quantum cryptographic communication services.
ISO/IEC JTC1* and ETSI are standardizing security specifications and evaluation methods for quantum key distribution devices, which are the most fundamental and important devices used in creating quantum key distribution networks. Toshiba, together with NICT and NEC, is participating in projects by both organizations to assist with this standardization process.
* ISO/IEC JTC1: A joint technical committee of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC)
In conjunction with this standardization, certification authorities in different countries are expected to create systems for evaluating and certifying quantum key distribution devices based on formulated standards, and device vendors are expected to use these systems.
In part 3 of this running feature, we have introduced quantum key distribution networks, essential for the real-world deployment of quantum cryptographic communication, and measures being taken to standardize these technologies. In the next issue, we will talk about the future of quantum cryptographic communication technology.
