Problems solved by technology

[0012]The main disadvantage of this scheme is the lack of a centralized control mechanism, no member node maintains a complete key topology, and it is difficult to ensure that each member node changes in the network topology maintain information consistency

Abstract

The key management scheme for virtual organization in grid computation environment comprises: generating and updating the key; communicating and identifying based on threshold scheme. Based on schemes of centralization and distribution, it provides a new layer-cluster key management frame to solve the security problem and improve execution efficiency.

Description

technical field [0001] The invention is a key management scheme for generating, distributing and updating group keys for each node of a dynamic virtual organization in a grid computing environment, and belongs to the cross-technical application field of grid computing and information security. Background technique [0002] Grid computing is a new type of computing mode specially aimed at complex scientific computing, which has developed rapidly along with Internet technology. This computing model uses the Internet to organize computers scattered in different geographical locations into a "virtual supercomputer", in which each computer participating in the calculation is a "node", and the entire calculation is composed of thousands of "supercomputers". "a grid" composed of "nodes", so this calculation method is called grid computing. The "virtual supercomputer" organized in this way has two advantages, one is super data processing capability; the other is that it can make fu...
