| 20090271632 | SECRET AUTHENTICATION SYSTEM - Authentication data indicating authenticity of a client is distributed into a plurality of function data as distributed data, the plurality of function data including function data specifying a function and rule data specifying the authentication data from the function. The client and a server shares a portion of the plurality of function data. The client calculates verification data from the function data unshared with the server, by performing a calculation process difficult for a third party to calculate the function data, and transmits the verification data to the server. The server verifies authenticity of the client based on the authentication data and distributed data per client stored therein, and the verification data received from the client. | 10-29-2009 |
| 20090276621 | SECRET AUTHENTICATION SYSTEM - An authenticated apparatus generates scrambled data from key data and authentication data, such that another key data, which configures the product data, or authentication data is obtained through back-calculation of the product data by using the authentication data or key data, the scrambled data including the product data and the like generated by multiplying the authentication data indicative of the authenticated apparatus's or a user's authenticity by the key data. The authenticated apparatus generates verification data through an operation of the authentication data, key data, or scrambled data, and transmits the verification data and scrambled data to an authenticating apparatus. The authenticating apparatus then verifies authenticity of the authenticated apparatus based on the verification data and scrambled data received from the authenticated apparatus and each authenticated apparatus's or each user's authentication data stored in the authenticating apparatus. | 11-05-2009 |
| 20090276622 | SECRET AUTHENTICATION SYSTEM - Authentication data is distributedly defined by a plurality of distributed data, including function data specifying a function. A portion of the distributed data is shared between an authenticated apparatus and an authenticating apparatus. The authenticated apparatus obtains verification data from the distributed data unshared with the authenticated apparatus, and transmits the verification data. The authenticating apparatus verifies authenticity of the authenticated apparatus, based on the verification data and the like received from the authenticated apparatus. The authenticated apparatus generates the distributed data containing predetermined control data, and transmits the distributed data to the authenticating apparatus. The authenticating apparatus extracts the control data from the distributed data containing the control data, and determines whether or not authentication is granted based on the control data. | 11-05-2009 |
| 20090285389 | ELECTRONIC CERTIFICATION SYSTEM AND CONFIDENTIAL COMMUNICATION SYSTEM - A first apparatus as a requester is configured to encrypt random number data by using a public key of a second apparatus as a certificate issuer; to perform a calculation that multiples original data by the obtained encrypted random number data; and to deliver the obtained random number scrambled original data to the second apparatus. The second apparatus is configured to perform a calculation that multiples the random number scrambled original data by certified item data; to encrypt the obtained random number scrambled original data having the certified item, using a private key of the second apparatus; and to issue the obtained certificate data to one of the first apparatus and another apparatus that performs verification. | 11-19-2009 |
| 20090307495 | CONFIDENTIAL COMMUNICATION METHOD - In SSL encryption communication in which a client and a server share a password, the client generates random number data, encrypts the random number data with a public key and a password, and transmits the encrypted random number data to the server, so that the client and the server safely share the random number data having a bit length longer than that of the password. Safe cryptographic communication is performed without intermediaries by using the random number data or by mutually presenting a hash value of the random number data. | 12-10-2009 |

| 20100209225 | SUBSTRATE TRANSFER ROBOT, SUBSTRATE TRANSFER DEVICE, SEMICONDUCTOR MANUFACTURING APPARATUS, AND METHOD FOR PRODUCING SEMICONDUCTOR - A substrate transfer robot includes a substrate gripping portion, an arm unit, and a controller. The substrate gripping portion is configured to hold a substrate. The arm unit includes a plurality of arms which are capable of turning in a horizontal plane. The arm unit has the substrate gripping portion at a leading end of the arm unit and is configured to transfer the substrate between a plurality of taught positions taught beforehand. When the taught positions are taught, the controller is configured to generate an access standby position corresponding to each of the plurality of taught positions and configured to generate and store a plurality of routes from the access standby position to a minimum turning posture of the substrate transfer robot. | 08-19-2010 |

| 20090028617 | FIXING APPARATUS, HEATING ROLLER, AND IMAGE FORMING DEVICE - There is provided a fixing apparatus capable of reducing the warm-up time, improving the heating efficiency, and suppressing the temperature increase out of the sheet width by using a magnetic adjuster. In this apparatus, the Currie temperature Tc of the magnetic adjuster material heated by electromagnetic induction is set to 220 degrees C. or below and the fixation setting temperature of a heating member corresponding to the portion where a recording material passes during continuous sheet feed is set lower than a value than the temperature at which the relative magnetic permeability of the magnetic adjuster material begins to decrease. Thus, it is possible to obtain a large difference between the heating portion and the non-heating portion, to surely prevent excessive temperature increase of the portion out of the recording material width, to reduce the warm-up time, and improve the heating efficiency. | 01-29-2009 |
