Abstract: The enormous world wide web and its application of sending data have caused a tremendous increase in stolen or attach the false data with the original data while sending from one node to another node through the intermediate nodes for that we have to securely send the data from source to destination. Virtual energy based encryption and keying has introduced an effective solution to the problem of detection of false data over the network. In the virtual energy based encryption and keying technique we introduced an concept is one time dynamic key (i.e.).The data which is to be send from source to destination is encrypted using the secret key and the encryption algorithm. The secret key is generated, one time dynamic key is employed for one packet only and different keys are used for the successive packets. Virtual energy based encryption and keying is a secure communication framework the data to be send is encrypted using the AES algorithm. The intermediate nodes are verified the incoming packets if the incoming packet is false packet injected in the network by the malicious outsiders those packets are detected and dropped otherwise the packet is forwarded to the next node. In the virtual energy based encryption and keying there are two modes of operations they are virtual energy based encryption and keying-I and virtual energy based encryption and keying- II. In the virtual energy based encryption and keying-I each node monitors their neighbor node and in the virtual energy based encryption and keying-II each nodes randomly choose the nodes and monitors those nodes. These two modes of operation monitor the nodes and detect the false packet and drop those false packets.
