    摘要： An in-vehicle gateway device (100) according to an arrangement includes a storage unit (130), a plurality of internal communication processors (111-116), a routing processor (120) and a storage controller (140). The storage unit (130) stores therein data output by an electronic control unit (12-20, 22) included in the in-vehicle system (10). The internal communication processors (111-116) include an internal communication processor to which at least one electronic control unit (12-20, 22) is connected. The routing processor (120) transfers data among the internal communication processors (111-116) and outputs at least a part of the transferred data to the storage unit (130) in a form capable of being stored in the storage unit (130). The storage controller (140) manipulates or filters, in accordance with a certain rule, at least one of the data to store in the storage unit (130) and the data output from the storage unit (130).

    摘要： An information processing apparatus has an authentication & key exchange unit, a contents receiver, a contents decryption unit and a contents confirmation request unit. The authentication & key exchange unit performs authentication & key exchange processing by using a given protocol with the communication apparatus and generates a first key shared with the communication apparatus. The contents receiver receives encrypted contents obtained by encrypting the contents with a second key generated by using the first key and the key information, and the key information attached to the encrypted contents. The contents decryption unit decrypts the encrypted contents by using the first key and the key information. The contents confirmation request unit instructs the communication apparatus to transmit or confirm the key information held by the communication apparatus, when the contents decryption unit decrypts the contents based on the second key firstly generated by using the first key.

    摘要： According to an arrangement, a data storage device (100) includes a data accumulation unit (180), a bus interface (160), and a processor (110). The processor (110) is configured to control operation of the data storage device (100) so as to spontaneously acquire data from an in-vehicle network via the bus interface (160) and store the data in the data accumulation unit (180). The processor (110) includes a message processing unit and a data access processing unit. The message processing unit is configured to transmit and receive messages, via the bus interface (160), to and from an electronic control unit or an external device connected to the in-vehicle network. The data access processing unit (116) is configured to command the data accumulation unit (180) to write and read data. Data included in a message received by the message processing unit is written in the data accumulation unit (180) in accordance with a command of the data access processing unit.

    摘要： A content recording apparatus (100; 1400; 1600) includes a reading unit (112) that reads, from a recording medium (140), a title key, a title content in plane text, an encrypted title content, an adjunct data, and a plain text adjunct data. The content recording apparatus (100; 1400; 1600) further includes a playlist generating unit (128; 1428; 1628) that generates a first playlist including the encrypted adjunct data and the plain text adjunct data, and generates a second playlist including only the plain text adjunct data. Each of the first playlist and the second playlist defines an order in which the title content as a playback target is to be played back. The content recording apparatus (100; 1400; 1600) further includes a recording unit (113) that records the first playlist and the second playlist onto the recording medium (140).
