Secure and scalable many-to-one symbol transmission for sensor networks

In secure many-to-one communications, a set of nodes transmit data to the same receiver. Research in this area focuses on increasing scalability by minimizing the amount of data reaching the receiver. Current proposals for secure many-to-one transmission use costly cryptographic operations. In this paper, we present a novel system for secure many-to-one symbol transmission in which nodes are only required to perform lightweight operations. This makes it suitable for implementation in resource-constrained scenarios such as sensor networks.
