Data aggregation in WSN (Wireless Sensor Network) is substantial in increasing the network lifetime by eliminating the information redundancy. However, in current practice, aggregation data is transmitted in clear hence the whole process is prone to various attacks. In the past, this unwanted pitfall was mostly due lack of efficient encryption technology suited for limited WSN nodes; however, relatively lightweight HES (Homomorphic Encryption Scheme) allowing operations on the encrypted data is considered as a promising solution in securing such constrained devices.
