The oxide layer is a layer of oxide including one or more non-noble metals as a main component. The first catalyst layer includes an oxide of noble metal including Ir and/or Ru as a main component. The second catalyst layer includes an oxide of noble metal including Ir and/or Ru as a main component. The first catalyst layer is denser than the second catalyst layer.

Abstract: An electronic control unit is configured to perform: allocating CPU resources to provide a plurality of virtual machines under a management by a hypervisor; monitoring an abnormality that occurs in one specific virtual machine by another virtual machine different from the specific virtual machine; outputting a stop request that requests stop of the allocation of the CPU resources to the specific virtual machine in a case that the abnormality is detected; and stopping allocation of the CPU resources to the specific virtual machine, by the hypervisor, in response to the stop request. The electronic control unit further comprises a DMA controller. The DMA controller transfers data transmitted to the specific virtual machine to a common memory which is common among a plurality of virtual machines.

Abstract: A vehicular system includes a first electronic control device that manages an encryption key, and a second electronic control device that uses the encryption key. The first electronic control device is configured to create the encryption key in response to that an owner of a vehicle has changed, and output the encryption key to the second electronic control device. The second electronic control device is configured to store a first encryption key and a third encryption key, receive a second encryption key, switch the encryption key being used, and update the first encryption key to the second encryption key.

Abstract: In an information processing apparatus and a method of controlling the same, settings for prohibiting an access to a removable medium is performed, and even if the setting is set, the access to the removable medium is permitted in a case where the information processing apparatus is activated in the maintenance mode.

Abstract: A control device in a vehicle: determines whether the control device is detached from the vehicle; communicates with other control devices mounted in the vehicle; stores an encryption key; performs a calculation process necessary for communication; and prohibits execution of the calculation process using the encryption key when determining that the control device is detached from the vehicle.

Abstract: A communication apparatus includes a counter, a reception portion, an update portion, a code generation portion, a determination portion, and a transmission portion. The reception portion receives a communication data from a different one of the communication apparatus. The update portion updates a value of the counter. The code generation portion generates a message authentication code based on the communication data received by the reception portion, the value of the counter, and a common key. The determination portion determines whether the message authentication code generated by the code generation portion matches a message authentication code set in the communication data. The transmission portion transmits a synchronization request when a number of times that the determination portion determines a mismatch between the message authentication codes becomes equal to or more than a predetermined number of mismatches.

Abstract: An information processing apparatus for performing encryption communication with an external apparatus by an encryption communication protocol has an inhibition unit for inhibiting use of a set of algorithms which do not satisfy a predetermined condition among a plurality of sets of algorithms used in the encryption communication protocol. The set of algorithms whose use if inhibited is a set of algorithms which need to transmit a message with a signature of the information processing apparatus to the external apparatus at the time of handshake performed with the external apparatus prior to the encryption communication.
