A segment encryption and transmission scheme for wireless sensor network

Some wireless sensor networks (WSNs) must transmit the data to users securely and quickly. The sensor nodes just have limited computation, communication and storage capabilities. Moreover adversary can easily eavesdrop in the process of message transmission, the data should be protected through encryption. In this paper, we present a new data encryption scheme for the transmission, which uses the lightweight cryptography and lets several sensor nodes to encrypt and transmit data cooperatively, thus it can lighten the load of single sensor node, ensure the communication security, provide good load balancing and a higher lifetime of the network.
