Safety protection method facing to mobile agent network management

Abstract

In hardware, smart cart is adopted as reliable execution environment of mobile agent; and in software, encryption techniques are adopted to ensure confidentiality and security of mobile agent and information of administer of network. Under management of validity and verification, executing task of managing network, the mobile agent is divided into public and private codes and data, which are protected by conventional encryption / decryption algorithm and encryption / decryption algorithm in published cryptographic key / secret code system. Kernel portion of mobile agent is executed in smart cart. From hardware and software synthetically, the method guarantees security of network management of mobile agent, lowers difficulty of security and protection, increases flexibility, configurability and expandability.

Description

technical field [0001] The invention is a security solution for applying distributed computing technology to an open network environment. It is mainly used to solve the security problems of network management based on mobile agents, and belongs to the cross-technical field of computer network, distributed computing and information security. Background technique [0002] In the current network management solution, most of the network management calculations are completed by the network management station. When using this method for network management, a large amount of information exchange between the management station and the managed nodes will cause a great waste of network bandwidth, and this solution cannot dynamically expand the server's ability. The above shortcomings can be alleviated by adopting the distributed computing technology of mobile agent. A mobile agent is a software entity with certain intelligence and judgment capabilities. It can migrate on a heterogen...

Problems solved by technology

[0008] (2) Active attack: ① Interruption: destroying the resources of the managed network or making it unavailable

② Tampering and retransmission: The mobile agent is intercepted by a malicious node before reaching the destination, and the node may modify the code or data of the mobile agent, and then send it to the destination node, which may lead to illegal changes to network configuration and management parameters

In the process of network management, the security problems faced by the management station are ① the returned mobile agent contains malicious code, ② the data brought back by the mobile agent is tampered or forged
