Load balancing is critical to the performance of parallel processing systems. It is more difficult for network systems such as NIDS and Web Servers, because they must preserve flow order. But traditional flow-based load balancing schemes of network parallel processing systems, such as LLF, cost much resource and introduce lots of communication overhead. With the rapid popularization of multi-core...
A synchronization method of adaptive backstepping sliding-mode control is presented based on the multiscroll chaotic systems with hysteresis nonlinear function and unknown parameters. The strategy is designed by a step-by-step procedure interlacing. At each step, a coordinate transformation, the design of a virtual control via a Lyapunov technique and the definition of a tuning function are derived,...
SMS4 is a 128-bit block cipher used in the WAPI standard for protecting data packets in WLAN. In this paper, a differential power analysis attack method on every byte of round keys is presented. Through this attack, the round keys of the last four rounds of SMS4 can be obtained, and then the 128- bit encryption key can be found out. The results of simulation experiments indicate that this attack is...
Current increase in network bandwidth raised an aggressive challenge in network security, and stateful packet inspection based security systems is playing a more and more important role. Recent advances in scheduling theory show that it is possible to reduce the expected mean response time of a queuing system, simply by changing the order in which we schedule the requests according to the job size,...
With the increase of network bandwidth, high performance protocol processing plays more and more important role in high speed network security. Recent studies show that current computer architecture advances and CPU performance improvements have limited impact on network protocol processing performance. Some studies find that in real SMT processor like Intel Xeon processor with hyper-threadings, the...
Intrusion detection is a critical component of secure information systems. Current intrusion detection systems (IDS) especially NIDS (network intrusion detection system) examine all data features to detect intrusions. However, some of the features may be redundant or contribute little to the detection process and therefore they have great impact on the system performance. This paper proposes a lightweight...
As more and more spam emails are continually increasing exponentially, both the Internet service providers (ISP) and the end users are suffering. Spam filtering is a classic puzzle in the field of network security. In this paper, we present a novel anti-spam technique standing at a unique point of view, which includes novel users' feedback mechanism, user-oriented classifier based on improved naive...
Tremendous increases in spam traffic have made an imperative to develop effective techniques that can filter Internet spam traffic for using in network operation and security management. In this paper, we propose a more effective scheme called improved bulk mail traffic classification (IBMTC) for filtering spam from bulk delivery E-mails traffic. Based on our earlier designed scheme, we further address...
