Next generation onboard information platforms are required so that information can be utilized through various onboard communication media and portable electronic equipment can be easily connected. The security system for their onboard information platforms has been studied. Various architecture of onboard information platforms have been compared, mainly PLANETS (PLatform for Automotive info NET System) which was proposed by JSK in fiscal year 2000, in terms of their degree of protection against threats (ex. unauthorized access) and costs. Using PLANETS architecture, which provides a high level of protection against threats, concrete examples of application and threats in AMI-C message sets have been studied and the specified security requirements have been tabulated. Furthermore advantages and disadvantages of two kinds of chosen security function layouts for the onboard information platforms have been studied. One is distributed to two gateways and the other is centralized to one gateway.
