Prevention of Key Based Attack on Data Sharing System

computer Engineering

Today security with respect to input data is play as an very important in the networking system. Key recovery is the difficult task in data sharing system. When authenticated user access the file then that user will get the file as well as the key to decrypt that file. But after some time interval if user found less trustworthy then data owner may block that user. The main problem is that user is still having the key so there may be possibility that user can share that key with others so to recover that issue data owner resign the particular file so even though the user try to leak the key then there is no issue of accessing the file. In this paper we proposed two type of key recovery Black box and Gray box key recovery. Many anomaly detection systems depend on machine learning algorithms to derive a model of normality that is later used to detect suspicious events.
