Design And Implementation Of SSL Based QTI-NG Network Security Management System

With the rapid development of Internet, Network Management application of isomerous network has increased fleetly in scale and complexity, shared data or communication between manager host and service provider host has gradually manifolded, this leaves the new security problem,all of this bring forward more and more new and advanced requirement for security of sensitivity resource and function.This paper take the project of"QTI-NG network management system"as background, combinewith my own task taked in hand in the project, consult the latest pertinent research production. it is achieved after lucubrate the network management of correlative issues. In this scheme, we point out the insufficiency in security after analyse the current security management system, bring forward the corresponding improvement measure, put forward a network security management framework aimed at NMS, then we discuss and describe the key technology especially the design and realization detailedly.SSL(Security Socket Layer) of JSSE(Java Secure Socket Extension) implementation and extention is part of the Java standard extention API. because SSL can provide bidirectional validation and data encryption,which satifies with the requirement of data integrality and secrecy. In this point it tallies with the trend of NMS demands which are aware of security much more. In addition , authentication and authorization framework of this system adopts the"shake hands mechanism of challenge"and"authorization model of fine granularity", as a whole it constructs the primary model of security management system. System carrys out the encrypted message and transfer,it provides available validation both sides, it can insure the security of data in NMS, it can do fine and strict access control based on user's popedom. it implements effective resource management in network management system.
