Inventor: KOBAYASHI MASAMITSU
IPC: G06F15/16
Filed: 1985-12-06
Abstract: PURPOSE:To speed up synchronization of all processors, and to execute an inter-processor synchronization at a high speed by generating a synchronizing signal by executing an access to a specified memory address of each processor, and setting a signal in case synchronizing signals of all processors have coincided, as a response signal of a memory of each processor. CONSTITUTION:In case a synchronization between processors is required, a CPU 21 issues artificially a memory access instruction to a specified address which does not exist on a memory 22, outputs a request signal to a request line 213, and loads its specified address on a data line 212. A decoder 23 is started by the request signal of the request line 213, and when the data line 212 shows a specified address, a synchronizing signal is outputted. Such a synchronizing signal is held by a latching circuit 24, and also sent out to a coincidence detecting circuit 5 through a synchronizing output line 214. At the time of the synchronizing operation, the same operation is executed by other processor, as well, and the synchronizing signals are sent out to the coincidence detecting circuit 5.

Title: Access authority transferring method
Inventor: HORIKIRI KAZUNORI
IPC: G06F21/31
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To safely transfer object-related authority information between subjects (users) in an object space in which service objects are scattered. SOLUTION: The user information and secret information of a client are shared between a client and a server. A client who transfers authority information generates authority information by weakening authority contents owned by himself or herself, and generates protected authority information which cannot be altered by a third person who does not know the secret information by applying a uni-directional function or ciphered function to a bit column obtained by connecting the generated authority information with the secret information. Thus, it is possible to safely transfer access authority by using the protected authority information. Further, the sever can safely confirm whether the client who issues a request for an object is authorized by analyzing the protected authority information by using the secret information.
