Characterizing mobile traffic is important to network operators from a network performance and security standpoint. In many cases, such as a performance degradation or security threat, it is useful to know that traffic is being generated by a specific mobile application. Recent methods for identifying mobile traffic have relied on computationally expensive detailed inspection of HTTP flows which may...
Utilizing computer aided security risk assessment, administrators can apperceive network security situation quickly and take countermeasures effectively. Most assessment methods disregard the dependencies among services, lack the evaluation against indirect risks, and seldom mention the composition of multiple source risks. Regarding the above problems, an assessment method that based on service dependency...
Traditional methods for evaluating network security neglect the correlation of network vulnerabilities. To solve this problem, a method based on Colored Petri Net (CPN) modeling is presented. Potential attack sequences are built according to the correlation of network vulnerabilities. The weakness and key paths can be found through analyzing the attack sequences. Simulation results show that the proposed...
Transmissions of large sized images can be a bottleneck for a wireless sensor network (WSN) due to its limited resources. Security can be another concern. This paper proposes a collaborative transmission scheme for image sensors to utilize inter-sensor correlations to decide the transmission and security sharing patterns based on the path diversities. Our proposed approach for secret image sharing...
