Patent Searching and Data


Title:
SUBSYSTEM AND METHOD FOR CONTROLLING ACCESS OF DECENTRALIZED COMPUTER SYSTEM
Document Type and Number:
Japanese Patent JPH06202998
Kind Code:
A
Abstract:

PURPOSE: To quickly perform request corroboration and to efficiently perform access control.

CONSTITUTION: A request is sent to a server from a requester as a message containing a first identifier given by the requester and a second identifier given from a corroborating agent. In each server process, the local cache of corroborated data discriminating a previous request to which a request message is corroborated is provided. Upon receiving the request, the server compares the first and second identifiers with the entry of a local cache. When the identifiers are coincident with the entry, it is understood that the request is corroborated. When the identifiers are not coincident, the corroborating agent of a server node is called and a corroborating credential for corroborating the request message is obtained. The record indicating that the message from a designated requester is corroborated is stored in the local cache and the corroboration of the received request is quickly obtained.
