Dear author,I have an example,when we use a new device or change the password to access the edge server,could it be judge the device is a malicious node,or it has a range to judge it is a malicious node or not?
In response to your question, since the new device has no historical access record, the security of the device cannot be preliminarily judged based on the past access record. Secondly, the behavior of changing the password will generate many attribute characteristics, such as the date and numbers of changes, which can help further determine whether the node is malicious. In this paper, to monitor whether the device is a malicious node, the comprehensive trust value of the node is weighted based on the direct trust value and the consensus trust value, which can be used to describe the reliability of the device.
