Energy is an igniting issue in the domain of wireless sensor networks. To overcome this issue, the technique of data aggregation is introduced. As the aggregator node collects data from many sensors so it becomes very interesting for compromisers. Unfortunately these aggregator nodes could be under the influence of various attacks. Under such circumstances, we have to make our data more secure, to protect it from adversary attacks. Proposed RSS (Re-Sequencing Scheme) provides secure data aggregation. It is based on symmetric key, information dispersal algorithm and multipath routing. Symmetric key is injected in the node at deployment time and it is shared only between the node and sink. Node sense data places it in buffer then disrupts the data sequence according to symmetric key. It splits data into many shares and routes them on multiple paths. On receiving, these aggregated shares are reconstructed by the sink and arrange the data in order, with the help of symmetric key. The RSS provides authenticity, data availability and protection against eavesdropping, data tampering and denial of service attacks, even in the presence of compromised nodes.
