A pre-existing partnership between the Japanese Government and Keio University paved the way for K-12 education to embrace distance learning. The university has been engaging in the revision of educational ICT policies in Japan for many years. In Japan, universities have been accumulating knowledge in distance learning practices since the emergence of the Internet, though earlier educational ICT policy required the ICT system in K-12 education to depend on dedicated Internet lines. In December 2019, the Japanese Ministry of Education, Culture, Sports, Science, and Technology (MEXT) announced a new ICT policy to allow K-12 education to launch distance learning classes via public cloud on the Internet. The university’s experience with running distance learning, bundled with the stipulations of the new educational ICT policy, enabled K-12 education to carry out distance learning. New subjects can be taught daily, and continuity of education is ensured in disaster situations, such as the Covid-19 pandemic. The research team at Keio University built the “Nagasaki-Takaoka Model” as a reference model with the added aim of ensuring data security and trust in the open network. In December 2020, Takaoka City successfully deployed the “Nagasaki-Takaoka Model” across all public schools.

Standardization of security protocols in hardware and software engineering is critical to implementing Virtual Power Plants (VPPs). The Cyber and Physical Security Framework presented by the Japanese Ministry of Economy, Trade, and Industry aims to align the implementation of DER devices with international standards for the configuration of products and services within the global supply chain. The requirement for trust in organizing, implementing, and securing DER systems informs the creation of a multi-tiered approach to gaining trustworthiness. In this report, CCRC provides the technology reference for DER system security in alignment with the above framework and suggests the best practices recommendations of security, authentication, and network with the application of various international standards.
