Abstract


With the extensive application of the Internet and the rapid development of the threat posed by the safety defect exists in the software , Trojans and other malicious software on the system security and data security has become increasingly serious . The traditional method to solve this problem is ongoing safety defect exists , the software upgrade, kill the horse virus continue to analyze the characteristics of the endless stream of Trojan virus . This paper presents a brand new release a security threat to the anti- Trojan technology . The experimental model is no longer concerned about the application running on the system if there are safety defect or whether it is a Trojan virus , but the data underlying the protection of data security and system security . Through monitoring and control operation in the application of the present experimental model , analysis by the execution of the application program a result of information flow, and to ensure that the application is running in a predetermined strategy . Once these applications beyond the authorized illegal data access request will be subject to the control of the experimental model . Follow the trusted computing base TCB (Trusted Computing Base) architecture of the experimental model as a basis for the use of the JAVA virtual machine , using dynamic bytecode injection technology , explore JAVA bytecode stream - based anti- instantiate objects dynamically add data labels Trojan anti-malware technology provides data security protection method . The experimental model is based on the object granularity dynamically modify the JAVA virtual machine running JAVA applications running class file does not change the original class file itself . Object data labels are also added to the JAVA application execution process , the unloading of the termination of the application object , the object data labels automatically separated . Different from the mechanisms and strategies of the JAVA virtual machine that comes with this experimental model , it can be more widely to detect and control the execution of Java applications according to the rules specified . In addition , the experimental model does not rely on a specific JAVA virtual machine implementation that can be run on a virtual machine of any support JAVA Virtual Machine Tool Interface (JVMTI) .
