Analysis of Crystals-Dilithium for BlockChain Security

Abstract

The emergence of quantum computers has threatened all the areas of internet security and privacy by providing an efficient solution to the underlying mathematical assumptions of the present cryptographic paradigms. The security of current internet applications utilizes this inefficiency in solving the above mathematical problems as a tool for security. One such prominent area where these security paradigms are at utmost core are Block-chains. They build a tamperproof network among trustless peers using these mathematical problems. Quantum attacks to applications utilizing blockchains pose a threat to a market worth 700 million USD. Therefore studies towards quantum secure blockchain are of utmost priority. Crystals Dilithium seems to be promising candidate for post-quantum blockchain security. This article reviews work done on this frontier and conclude Crystals-Dilithium relevance for quantum secure blockchains.
