Future of Quantum Computing in Cyber Security

Abstract

Quantum computing leverages the probabilistic nature of the universe to harness computing capabilities, superseding classical and even supercomputers to solve complex problems in areas including drug development, financial modelling, etc. It is all about metadata and algorithms. This chapter per the authors aims to examine the field quantum computing in the context of cybersecurity. Through a thorough study of the timeline of developments in cybersecurity, modern cybersecurity schemes have been examined and conclusions pertaining to their vulnerabilities due to the emergence of quantum computers have been drawn. Breaking modern cryptographic schemes is equivalent to solving the underlying mathematical problems that these schemes are based on, which can be significantly sped up with a quantum computer. Hence, this chapter conveys the need for enterprises to adopt post quantum cryptographic schemes, which are not easily vulnerable to attacks by a quantum computer.
