  • Abstract Wireless sensor networks have received a lot of attention in recent years. They are widely
    used because of the convenience, small volume and low cost of sensor nodes. Since most
    of the wireless sensor networks transmit data in open area, it results in critical concern of
    privacy and security when applying sensor networks. In order to prevent the existence of any
    eavesdropper from obtaining the output signal of either the sensor nodes or the relay nodes,
    the data transmission from both the sensor nodes and the relay nodes are encrypted in our
    system. Specifically, we employ the bit-flipping mechanism to encrypt the data transmission.
    Notably, in the thesis, we consider the eavesdroppers can combine the information eaves-
    dropped from both the sensor nodes and relay nodes. As a result, the optimization problem
    considered in this thesis is to choose the best bit-flip encryption method, such that the legitimate
    fusion center can achieve the smallest probability of detection error while the eavesdropper’s
    error detection probability is higher than a required value.
