A Lamus-Based Flight Data Sharing Model on Consortium Blockchain

Currently, traditional flight data sharing models cannot resist quantum attacks, which poses the risk of leakage. The research on model against attack has become one hotspots. Lattice-based cryptography is recognized as an effective way to attacks. A consortium blockchain proposed in this paper resolve leakage during sharing. First, a new lattice-based multisignature scheme (Lamus) proposed, capable resisting We prove security Lamus random oracle model. Moreover, by applying Security and performance analysis show that guarantees antiquantum security, it achieves good terms storage efficiency operating efficiency.
