To enhance medical cooperation between the hospitals and clinics around Osaka local area, the healthcare network system, named Osaka Community Healthcare Information System (OCHIS), was established with support of a supplementary budget from the Japanese government in fiscal year 2002. Although the system has been based on healthcare public key infrastructure (PKI), there remain security issues to be solved technically and operationally. An experimental study was conducted to elucidate the central and the local function in terms of a registration authority and a time stamp authority in contract with the Japanese Medical Information Systems Organization (MEDIS) in 2003. This paper describes the experimental design and the results of the study concerning message security.
为加强大阪地区周边医院和诊所之间的医疗合作，在日本政府2002财年补充预算的支持下，建立了名为大阪社区医疗信息系统（OCHIS）的医疗网络系统。尽管该系统基于医疗公共密钥基础设施（PKI），但在技术和运营方面仍存在安全问题有待解决。2003年，与日本医疗信息系统组织（MEDIS）合作，进行了一项实验研究，以阐明在注册机构和时间戳机构方面的中央和地方功能。本文描述了有关消息安全的实验设计和研究结果。
