摘要： An information processing apparatus that executes a program includes: a storage unit that includes a first region and a second region in which different versions of the same type of program are rewritably stored; and a computation unit that executes the program stored in the storage unit, in which each of the first region and the second region stores the program and up-to-dateness information regarding up-to-dateness of the program, the information processing apparatus determines whether or not to update the storage unit with the program based on the up-to-dateness information received together with the program to be updated, and the information processing apparatus starts the program with the up-to-dateness information indicating higher up-to-dateness among the programs stored in the respective regions.

摘要： Provided is a gateway device capable of reducing influence on intra-vehicle network communication from a cyber security attack that infringes availability represented by a DoS attack from an extra-vehicle network. Included are: an external-network-side transfer processing unit that transfers a communication frame received from an external network to an internal network; an internal-network-side transfer processing unit that transfers the communication frame transferred from the external network via the external-network-side transfer processing unit to the internal network; a transfer notification unit that gives a transfer notification to notify transfer of the communication frame from the external-network-side transfer processing unit to the internal-network-side transfer processing unit; and a monitoring unit that determines whether to transfer the communication frame based on at least one of a frequency of the transfer notification to the internal-network-side transfer processing unit and a transfer data amount of the communication frame transferred from the external-network-side transfer processing unit.

摘要： An information processing device that executes a program includes: a storage unit that includes a plurality of regions for storing a rewritable program; a calculation unit that executes a program stored in the storage unit; a start region specification unit that specifies, from the plurality of regions, a start region in which the calculation unit is executing a program; a rule update unit that specifies a rewrite target region in which a program can be rewritten based on information on the specified start region; and a reception selection unit that selectively receives a rewrite program stored in the rewrite target region.
