Abstract: An information processing device includes a malicious message detector and an outputter. The malicious message detector detects a malicious message in a network based on an SA included in a claim message received from the network, a period that is based on a time at which the claim message is received, and a message received from the network before or after the claim message. The outputter outputs a detection result of the malicious message detector.

Abstract: A function update method improving household appliance functions by enabling new and existing household appliances to perform cooperative processing. In the method, a server stores registration information listing identification information for each household appliance owned by a user, combination information listing combinations each including household appliances performing cooperative processing, and update information for each household appliance in each combination, for updating a function for performing the cooperative processing. The method includes: receiving, from a household appliance having identification information not listed in the registration information, a request to list the identification information in the registration information, and listing the identification information in the registration information; selecting a combination listed in the combination information, the combination including the household appliance and all other household appliances in the combination being registered in the registration information; and transmitting update information to each household appliance requiring a function update in the combination.

Abstract: A data processing device for playing back a digital work reduces the processing load involved in verification by using only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on a DVD. In addition, the data processing device improves the accuracy of detecting unauthorized contents by randomly selecting a predetermined number of encrypted units every time the verification is performed.

Abstract: A server includes: an obtainer that obtains items of information including an item of frame information regarding a communication frame transmitted on an in-vehicle network of each of a plurality of vehicles; and a generator that generates an integrated rule that is suitable for the items of information obtained by the obtainer and is for anomaly detection processing in the in-vehicle network of one of the vehicles; and a provider that outputs the integrated rule generated by the generator. For example, the obtainer obtains condition information indicating a condition pertaining to each of the plurality of vehicles at a time when the communication frame is transmitted on the in-vehicle network, and the generator generates the integrated rule using the items of frame information associated with the condition information.
