Lattice Based Cryptography Implementation in Blockchain Technology

Abstract

The lattice-based encryption is one of the most appropriate choices to secure the blockchain technology during the post-quantum era withstanding security against a quantum adversary attack. The authors study lattice-based cryptography and integrate it with the blockchain architecture in order to address gaps that have recently been exposed because of the continued advances with quantum systems. However, a majority of the classical cryptographic designs such as RSA and ECC are designed around the difficulty of particular mathematical problems, one of which is the Shor algorithm, which makes them highly susceptible to quantum algorithms. Learning with Errors (LWE) and Short Integer Solution (SIS). The paper will discuss the feasibility of lattice-based digital signatures, zero-knowledge proofs, and encryption systems that should be deployed in blockchain so that the integrity of data should be maintained, transactions should be secure, and privacy of users should be preserved. Furthermore, it introduces performance features of blockchain where it considers the lattice-based cryptographic systems where it entails scalability, complexity of computing, and latency. The results are then employed to support the options of encryption with lattices to lay the groundwork for the architecture to quantum-resistant blockchain-based frameworks, and the ultimate stage of secure and scalable decentralized networks in the post-quantum world.
