Implicit trust of data is a major problem with using artificial intelligence or machine learning for CPS security, because during critical attack detection time they are more at risk, with greater likelihood ...
Using this model, a location-cum-domain based fusion framework is proposed and evaluated with different combination rules, that fuse multiple evidence from inter-domain and intra-domain sensors. ...
Specifically, two advantages we achieve from D-S theory are (1) its ability to deal with the lack of prior probabilities for various events and (2) its ability to combine evidences from multiple sources ...
