Executive Summary

In wireless sensor networks, in-network data processing plays an important role to reduce the transmitting energy and data redundancy in large-scale sensor networks. However, the security of wireless sensor networks is a challenging problem with the compromised sensor nodes in the networks. This paper introduced a trusted secure in-network data processing schema to enhance the data security of wireless sensor networks. The secure in-network processing tree is constructed firstly, then a judgment method based on trust schema was used to detect whether a sensor node has potential misbehavior. A detecting algorithm is used to searching abnormal data from the reporting reading of sensor nodes.
