Abstract: 在数据库受到攻击的情况下,保证关键业务的持续服务和动态恢复入侵造成的破坏是非常重要的问题。当前很多中小型网络数据库并无冗余机作为后备,但又必须采用客侵机制采保证其可用性和安全性,所以本文提出了一个基于角色访问的非冗余容侵数据库结构。谊结构能通过隔离执行关键数据采提供不问断的关键业务服务;对于入侵能够在线进行自动恢复;根据用户的角色、历史记录和容侵要求,自动进行状态迁移和系统参数调节等。

Abstract: Nowadays, IP networks are suffering many faults and malicious attacks which greatly threaten its security and survivability. So it is an important issue that how to make the IP networks to be more robust under faults and attacks, i.e., to improve their tolerance abilities for both fault and intrusion. However recently, most of the researches focus on only one of them, and decouple the survivability and security each other. According to the trust model in social networks, this paper proposes an efficient fault-tolerant and intrusion-tolerant scheme based on trust relationship for IP networks. This scheme not only borrows the trust rating from the social links, but also qualitatively describes the relationships between the trust rating and the network behavior. Then, this paper analyses the scheme how to tolerate three known malicious behaviors, viz., self-faults, bad mouth attacks and conflict behavior attacks. Finally, the numeric simulation results show that the scheme can detect the malicious nodes fast and accurately and efficiently prevent these malicious behaviors in IP networks.

Abstract: Aiming at the absence of self-adaptation ability and quantitative analysis on existent intrusion tolerance system,this paper proposed an adaptive hierarchy intrusion tolerance system based on autonomic computing (AHITAC).Adopting hierarchy modes, the critical modules of AHITAC included confidence evaluation of accessing, active trapping on suspicious information, hierarchy study of applications and classed recovery of system function. By implementing the study and adaptive function of confidence threshold, service classification and trap repository, AHITAC implemented the tolerance on intrusion and suspicious information, improving the ability of self recovery and self optimization on object network. The simulation results show that the object network with AHITAC is stable and tolerant.

Abstract: Secret sharing is one of the new subjects of cryptography. As the theory of secret sharing developed, it is used in secure group communication more and more regularly. It enhanced the security,robust,integrity and the efficiency of communication. In this article, the theory of secret sharing is first showed, then its applications in threshold schemes,group communication,key escrow,digital authentication and intrusion tolerance system are introduced. At last, the direction of future research is proposed.

Abstract: This paper presents the process for research and implementation a real-time duplicate software in DB2 database. This software used the modular design, and has 5 major modules: Client, Server, Full synchronizing, Increase synchronizing, Load. While the software running, the 5 modules coherent on with another. The client call the server, and the server schedules all task. In the process of the implementation, we grap the database's log real-time to gain the change. This software doesn't use any DB2 database's backup interface, so it well done in the function and efficiency. The test environment is OS:LINUX, CPU:Core 2.4 GHz ,Memory: 2 GB. Under such a test environ-ment, this software worked well.

Abstract: Aiming at the limitation for intrusion-tolerant and self-healing, this paper presented a self-healing intrusion-tolerant model based on J2EE application server, and presented an self-healing intrusion-tolerant method for this model. Compared with the traditional method, this method not only solved the limitation for intrusion-tolerant, for example,the hidden intrusion, software aging, and the vulnerable prerequisite of intrusion tolerance, but also solved the problem of intrusion in the self-healing. Finally, comparison tests of the self-healing intrusion tolerance clusters,JANTM clusters and J13oss4. 0 clusters verify the self-healing intrusion tolerance method to make self-healing intrusion tolerance clusters higher reliability and survivability.
