Data hiding method based on color table expansion technique by FEI Ru-chun1, WANG Li-na1, ZHANG Huan-guo1

“…Based on color table expansion technique for indexed images,a data hiding method was proposed,and the se-curity and the hiding capacity were analyzed.The analysis results show that this method has very strong security and very high hiding capacity.Secret data can be hidden in an indexed cover image to generate a stego-image with the same visual effect as the cover image and resumed without distortion from the stego-image if the correct key is used.In addition,the statistical feature of the secret data is completely covered up by using random data,so the stego-image is statistically in-dependent of the secret data.…”

Network security situation evaluation method for multi-step attack by Hao-pu YANG, Hui QIU, Kun WANG

“…Aiming at analyzing the influence of multi-step attack,as well as reflecting the system’s security situation accurately and comprehensively,a network security situation evaluation method for multi-step attack was proposed.This method firstly clustered security events into several attack scenes,which was used to identify the attacker.Then the attack path and the attack phase were identified by causal correlation of every scene.Finally,combined with the attack phase as well as the threat index,the quantitative standard was established to evaluate the network security situation.The proposed method is assessed by two network attack-defense experiments,and the results illustrate accuracy and effectiveness of the method.…”

Aeronautical Ad Hoc network node failure analysis method by Lixia XIE, Liping YAN, Hongyu YANG

“…To analyze the stability changes of aeronautical ad hoc network (AANET) caused by node failure affecting reaction effectively, an AANET node failure analysis method was proposed.Firstly, the model of business-entity asymmetric dependent network was established based on the characteristics of AANET.Secondly, an improved failure traffic redistribution algorithm was designed to obtain the affected node set.Finally, the AANET affecting impact value was calculated according to the node weight, then the affecting impact degree was determined.The experimental results show that the proposed method has better accuracy in the failure affecting impact analysis of AANET.…”
