According to one embodiment, an authenticator which authenticates an authenticatee, which stores first key information (NKey) that is hidden, includes a memory configured to store second key information (HKey) which is hidden, a random number generation module configured to generate random number information, and a data generation module configured to generate a session key (SKey) by using the second key information (HKey) and the random number information. The authenticator is configured such that the second key information (HKey) is generated from the first key information (NKey) but the first key information (NKey) is not generated from the second key information (HKey).

Authenticator, authenticatee and authentication method

An in-vehicle gateway device according to an embodiment includes a storage unit, a plurality of internal communication processors, a routing processor and a storage controller. The storage unit stores therein data output by an electronic control unit included in the in-vehicle system. The internal communication processors include an internal communication processor to which at least one electronic control unit is connected. The routing processor transfers data among the internal communication processors and outputs at least a part of the transferred data to the storage unit in a form capable of being stored in the storage unit. The storage controller manipulates or filters, in accordance with a certain rule, at least one of the data to store in the storage unit and the data output from the storage unit.

In-vehicle gateway device, storage control method, and computer program product

According to an embodiment, a reading apparatus is connectable with an information processing apparatus connected to a server apparatus. The reading apparatus includes an authenticator, a cryptographic processor, and a transmitter. The authenticator acquires a shared key by performing an authentication/key exchanging process with the server apparatus. The cryptographic processor acquires secret information and encrypts the secret information using the shared key. The transmitter transmits the encrypted secret information to the server apparatus.

Information processing system, reading apparatus, information processing apparatus, and information processing method

According to one embodiment, an authentication method between an authenticatee which stores key information having a data structure composed of a key transition record, secret information XY of a matrix form, and secret information XYE which is created by encrypting the secret information XY, and an authenticator which authenticates the authenticatee, includes selecting, by the authenticator, a record corresponding to a device index of the authenticator from the key information which is received from the authenticatee, and decrypting the record by a device key, thereby taking out a key transition, and executing, by the authenticator, a decryption process on the secret information XYE, which is received from the authenticatee, by using the corresponding key transition, and sharing the secret information XY.

Sulfonamide compounds having TRPM8 antagonistic activity are provided. A sulfonamide compound of formula (I) or a pharmaceutically acceptable salt thereof, or a prodrug thereof: wherein Ring A is bicyclic aromatic heterocycle comprised of (a) pyridine is condensed with benzene; or (b) pyridine is condensed with monocyclic aromatic heterocycle, and Ring A binds to a sulfonylamino moiety on a carbon atom adjacent to a nitrogen atom of the pyridine ring constituting Ring A,

Sulfonamide compounds having TRPM8 antagonistic activity

The present invention provides novel sulfonamide compounds having TRPM8 antagonistic activity which are useful as medicaments. Specifically, the present invention provides a sulfonamide compound of the formula (I): wherein Ring A is the following formula (i), (ii), or (ix):  Ris optionally substituted alkyl, Xand Xare each independently tetrazolyl, tetrazolinonyl, optionally substituted triazolyl, triazolinonyl, oxadiazolonyl, optionally substituted alkanoylaminomethyl, or optionally substituted alkylsulfonylaminomethyl, or Rand Xcombine with each other at their terminals together with the adjacent benzene to form indazolinonyl or benzoisoxazolonyl, and the other symbols are the same as described in the specification, or a pharmaceutically acceptable salt thereof.

Sulfonamide compound

According to one embodiment, an information processing apparatus, which is connected to an external apparatus, includes a device key storage unit, a creating unit, a calculating unit, a communication unit, and a key calculating unit. The device key storage unit stores therein a device key. The creating unit creates a media key from the device key and a media key block. The calculating unit calculates first output information on the basis of first inherent information inherent to the information processing apparatus and public information. The communication unit transmits the first output information to the external apparatus and receives second output information calculated by the external apparatus from the external apparatus. The key calculating unit calculates a shared key shared between the information processing apparatus and the external apparatus on the basis of the media key, the first inherent information, and the second output information.

Information processing apparatus and program product

A controller is provided with a controller key and a first controller identification information unique to the controller. The controller generates a controller unique key unique to a respective controller based on the controller key and the first controller identification information, and a second controller identification information based on the first controller identification information. A decryptor decrypts the encrypted medium device key using the controller unique key to obtain a medium device key. An authentication/key exchange process unit performs authentication/key exchange process with the host device through an interface unit using the medium device key and the medium device key certificate to establish the secure channel.

Information recording device

According to one embodiment, a memory chip, which is connected to a controller that controls reading and writing of data in response to a request from an external device, includes: a memory including a special area that is a predetermined data storage area; a key storage unit that stores therein a second key that corresponds to a first key used by the external device to convert the data; a converting unit that receives, from the controller, data to be written into the special area and generates converted data by converting the data to be written using the second key; and a writing unit that writes the converted data into the special area.

Memory device for converting data received from controller controlling reading and writing of data

A controller is provided with a controller key and a first controller identification information unique to the controller. The controller generates a controller unique key unique to a respective controller based on the controller key and the first controller identification information, and a second controller identification information based on the first controller identification information. A decryptor decrypts the encrypted medium device key using the controller unique key to obtain a medium device key. An authentication/key exchange process unit performs authentication/key exchange process with the host device through an interface unit using the medium device key, the medium device key certificate and the second controller identification information to establish a secure channel.

Data recording device, and method of processing data recording device

The data storage portion stores an encrypted medium device key Enc (Kcu, Kmd_i) generated by encrypting a medium device key (Kmd_i), a medium device key certificate (Certmedia), and encrypted content data generated by encrypting content data, the controller stores a controller key (Kc) and first controller identification information (IDcu), the information recording device being configured to execute, after being connected to an external host device, an one-way function calculation based on the controller key (Kc) and the first controller identification information (IDcu) to generate a controller unique key (Kcu) used when decrypting the encrypted medium device key Enc (Kcu, Kmd_i), and second controller identification information (IDcntr) used when decrypting the encrypted content data.
