摘要： Upon applying a DRM protection process to an image which is generated by an image processing apparatus, which doesn't have any communication means that allows direct communications with a PC, without any alteration, encryption of the image in the apparatus and that of the image in the PC as an internal process of the DRM are required, resulting in poor efficiency. The apparatus executes a part of the DRM protection process for the image, and outputs the encrypted image. The PC receives the image which has undergone the part of the DRM protection process, executes the remaining part of the DRM protection process, and outputs the image which has undergone the DRM protection process. In this case, the PC transmits use condition of the input image to a license server, receives signed use condition from the server, and combines the signed use condition with the input encrypted image.

摘要： It is possible to safely constitute a key management method having an access structure equivalent to the hierarchical key management method with a small amount of calculations. The method includes: a setting step for setting a set (,) of the number of times a one-way hash function is executed for each of the elements of the rank i; a key generation step for generating two separate keys for the elements as the value of the number of times the one-way function has been executed corresponding to the set of the number of times which has been set for the elements of the two original keys for each of the elements; and a key delivery step for delivering the two separate keys for the elements to each of the elements. Furthermore, the method includes an initial key generation step for calculating N keys with a route node positioned at the most significant node when generating a key at each node from a parent node and performing key delivery according to the hierarchical relationship expressed in a directed graph having no cycle; and a node key generation step for generating the value of the number of predetermined times the one-way function is executed according to the execution specification for M keys (M≦N) among the N initial keys in each node, as the M node keys for the node.

摘要： To include a plurality of core chips to which different pieces of chip information from each other are given in advance. A first refresh command is divided into a plurality of second refresh commands having different timings from each other, and a refresh operation is performed on a core chip for which a count value of the second refresh commands and at least a portion of the chip information match each other. With this configuration, even when the second refresh command is commonly supplied to a plurality of core chips, it is possible to shift a timing for the refresh operation in each of the core chips. Therefore, it is possible to reduce a peak current at the time of the refresh operation.

摘要： In one embodiment, a semiconductor memory device receives a refresh command and address information, and supplies a refresh control signal and the address information in common to core chips. Each of the core chips includes a layer-address comparison circuit that determines whether the address information assigns an own core chip, and a refresh control circuit that refreshes an own memory cell based on the refresh control signal when the address information assigns the own core chip. With this arrangement, a memory capacity of a chip that is refreshed by a refresh command for one time is reduced, and therefore a shortest issuing interval of a refresh command can be shortened.

摘要： A method for manufacturing a dental implant including an abutment is manufactured through the following steps. A titanium molded body production step molds a titanium molded body composition to obtain a titanium molded body having one of male and female thread portions. A ceramic molded body production step molds a ceramic molded body composition to obtain a ceramic molded body having the other thread portion which makes thread coupling with the one thread portion. An assembling step assembles the titanium molded body and the ceramic molded body together so that the one thread portion makes thread coupling with the other thread portion, to obtain an assembled body. A degreasing step degreases the assembled body. A sintering step sinters the degreased assembled body.
