In recent days Cyber attacks have become common threat which is leading to exploit data confidentiality. Spoofing is a common technique which is used by the attackers to make themself unidentified and probe towards phishing the data from target machines. So to make the data not influenced to phishing and the nodes in the network are not subjecting to spoofing we use a mechanism called pilot signal which is used with Channel state indicator. When we like to send data from the source to receiver we use a mechanism called pilot signal which is used like a strobe to the node in the network and estimates the channel state having the genuine internet protocol address. We maintain uplink and downlink paths for the nodes. We set frequency energies to the node at the time of adding it to the network, these frequencies are used to send and receive the signals throughout the network. By using CSI in the downlink and uplink paths the difference in the frequency is calculated to detect a spoofing event over a node if the received parameters are in un order to the standard frequency which is aligned earlier we treat it as detection of spoofing attack. The detection probability is evaluated based on the derived parameters of CSI from a node at a given requirement on the less probability of false alarming. The achievable secrecy rate is utilized to measure the security level of the data transmission. Our analysis shows that even without any pre-assumed knowledge of eavesdropper, the proposed scheme is still able to achieve the maximal secrecy rate in certain cases. our scheme could achieve a high detection probability as well as secure transmission.
