Abstract


With the rapid development of the Internet and information technology , it is in the sharing and use of information resources in the network , but the network security issues become increasingly severe . Could lead to network attacks , illegal invasion , all the critical information outside of the application systems diarrhea and other problems , this paper design a secure transmission of the improved model based on RBAC authorization management system . First, according to the basic principle of the PKI , the establishment of a transmission channel of information security . Combined through the PKI the Core Certification Center CA issued digital certificates and SSL protocol , the DES algorithm to encrypt information speed and quickness , combined with the RSA algorithm high security and key distribution advantages of flexible , user authentication of security channel encrypted transmission of information . Secondly, RBAC96 ARBAC97 model as a template , proposed based on the departments structure DRBAC rights management model . The model uses the Struts framework technology based and set permissions ideological system departments according to the needs of the practical application of the system , establish a specific role in the foundation of the department permission set permission dynamically allocated and peel , and also to achieve a combination of distributed and centralized authorization management permissions management . Once again, the use of the Spring framework AOP programming techniques , development of audit log system analysis and early warning . The audit log system to the rear aspect classes notification the record legitimate access information using surround notice of unauthorized access to the user's access to the records . Illegal access to statistics based on the analysis of a dangerous users sensitive to the risk of the user path , able to analyze the dangerous path based on the statistics of a particular path dangerous users , to provide further protection for system security . This system can be a good solution to the network application system authentication , secure transmission of data and access control .
