| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Managed blockchain platform services are being applied to enterprise systems to accelerate the development of blockchain applications. In conventional blockchain platform services, if service vendor executes the generation of the private key unique to the participating organizations that is required to construct blockchain network, the risk of unauthorized transaction execution by the vendor occurs. To prevent this risk, we suggest to place the private key of the participating organization on an external hardware security module (HSM) so that the service vendor cannot directly refer to the private key, and to introduce an audit tool to detect the unauthorized use of the private key by the service vendor. | |
