Embodiment Construction

[0097] The present invention will be described in more detail according to the drawings and embodiments below.

[0098] according to figure 1 and figure 2 , the present invention is a systematic mobile agent network management-oriented security protection method, from the creation of the mobile agent in the network management station, to the execution of network management tasks in the managed node, and finally returning to the network management station to submit information, the entire network management process are all protected.

[0099] For the convenience of description, we assume that the mobile agent performing network management tasks needs to visit n managed nodes, and the Java card of each managed node stores the key of the conventional encryption and decryption algorithm and the two involved in the encryption and decryption algorithm of the public key cryptosystem. A key, let the key of the conventional encryption and decryption algorithm be K, and the encryptio...

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...
