Negative selection mechanism in virus detection model is improved by optimizing the configuration of variable radius detector in this paper. The radius of the detector is configured automatically, and the contradiction between the number of detectors and its detection range is resolved. The immune system has better adaptability and dynamic in this paper.
Based on the specific features of advertisement robot widely existing in network information, a mixture strategy for network content filtering is presented in this paper. The strategy can determine quickly by calculating the fingerprint of network content, and Bayesian filtering is reused when the strategy can not determine. The result of this experiment shows that the strategy is more advanced than...
The diversification and intelligent of hackerspsila attacks makes it hard for single intrusion detection measure to attain favorable detection result. Therefore, it becomes one of the new hot spots in current research that how to combine multiple security measures to provide the network system more effective protection. A new computer information security protection system based on data fusion theory...
Mobile e-commerce is a new e-commerce branch and the new form of development of e-commerce. However, due to constraints in the development of mobile e-commerce payment security problem has not been soluted, mobile e-commerce applications are still on the surface. This paper, in such circumstances, first of all, introduces transactions mode from the view of safety of mobile e-commerce, and mobile e-commerce...
Survivability is the essential ability of a system to fulfill its mission, in a timely manner, in the presence of attacks, failures, or accidents. Survivability should be considered beyond security for information system, and quantitative analysis can assess system survivability accurately for improvement. The paper presents a new type of analysis method for computer system survivability which considers...
