A NTRU Lattice Edge Aggregation Scheme Based on Underwater Acoustic Communication

With the rapid development of communication technologies in marine environments, the privacy and integrity of transmitted data have become important security issues. The security and resource consumption of existing privacy-preserving data aggregation schemes are not suitable for application to underwater acoustic communications. To address the above issues, this article proposes an NTRU lattice edge aggregation scheme based on underwater acoustic communication. Specifically, the scheme protects the data by perturbing it through edge differential privacy, and then encrypts the perturbed data using a lattice-based encryption method. In addition, it utilizes the NTRU lattice-based batch signature verification method to verify signatures in batch, which improves the verification efficiency. The pseudo-identity of nodes and timestamps are also utilized to enhance the security of the scheme. The edge computing model is utilized to reduce the high delay in underwater acoustic communication and to reduce the wastage of the resource in the underwater acoustic communication. Security and performance analysis conducted through simulation experiments show that our scheme is resistant to quantum attacks and achieves differential privacy with low computational and communication cost overheads.
