Post Quantum Secure Blockchain Architecture for Data Dissemination
摘要
Post quantum cryptography is the key idea to resist quantum attacks. The Fiat-Shamir were the first who introduce efficient lattice-based signatures. A lattice-based signature ensures the security of blockchain architecture against quantum computers. However, a blockchain is always consisting of multiple communicating nodes, so there is a need to develop a verification method for multiple nodes. We have proposed a blockchain using module lattices. Blockchain security relies upon two assumptions, (1) Module Learning With Errors and (2) Module Short Integer Solution. The system can provide security against quantum attacks.
