End-to-End (ETE) encryption for Wireless Sensor Networks (WSN) is a challenging problem. To save the overall energy resources of the network it is agreed that sensed data need to be consolidated and aggregated on their way to the final destination. For such circumstances, this work presents an approach that conceals sensed and aggregated data end-to- end. The main aim of the proposed system is to consider WSNs in which messages should be transferred in a confidential way. More precisely, adversaries who eavesdrop communication between the sensors, aggregators and the sink should not obtain the exchanged information. It is considered that adversaries can at least carry out ciphertext-only attacks. However, the application will analyze available solutions according to their protection against more powerful attacks. The application is shown to evaluate the security threats in terms of links, keys, and route parameters on the basis of intensity of infection created by the attacker...
