In order to solve the problem of data aggregation and data transmission in wireless sensor network

a Multipath Data Transport (MDT) algorithm based on secure data aggregation and data reconstruction was proposed in the paper. The algorithm allows the network nodes exist in a few compromises

but also allows the loss of part of the data. The theory analysis and simulation result showed that the sensor network with the MDT algorithm could protect against availably eavesdropping

data tampering and Denial of Service attacks. The security and reliability of the network were improved.
