Quantum Computing harms the safety of data

With no real timescale for the arrival of quantum computers, tech companies are keen to get out in front of the potential challenges to current cybersecurity systems, before they become reality. In an announcement on 21 February, 2024, Apple unveiled what it called, “a groundbreaking ”. The company says its “PQ3” security system is designed to protect data sent over its iMessage platform. Apple claims its system offers protection against “even highly sophisticated quantum attacks”. Apple says it’s introducing this post-quantum encryption now to protect against what is known as “harvest now, decrypt later” attacks, where cybercriminals collect masses of data with the intention of decrypting it when the technology becomes available. and has already adopted them to protect the company’s internal communication. Google says that introducing new cryptography systems is in itself risky, citing examples of protocols that were cracked by conventional computers. Protecting the global economy The responsibility to protect essential systems from bad actors using quantum computers will extend far beyond tech companies. In 2022, the World Economic Forum, in partnership with Deloitte, produced . The research states: “Developing a coherent approach for transitioning to a quantum-secure economy requires a broad, collaborative and critical approach from a diverse and global community of business and cybersecurity leaders”. It also addresses the need for a set of governance principles and values as a way of “building trust in the technology and to pre-empt possible risks before the technology is commercialized”. These governance principles include commitments to cybersecurity, privacy and accountability. Building on these principles, designed to help organizations navigate the journey towards cybersecurity in an age of quantum computing. The toolkit urges leaders to factor in quantum-cyber protocols across corporate ecosystems and ensure there is collaboration in identifying risk and adopting protections. There is little doubt that quantum computing has the potential to help us solve some of the greatest challenges we face. But without adequate controls in place, it could also undermine the safety and security of data and communications beyond anything we have seen before.
