Modernizing Cryptography: Addressing the Quantum Threat and More

**[Video Title: Quantum Computing and its Threat to Cybersecurity – Explained]**

—
**Description:**

Welcome to our channel! In this video, we dive into the basics of quantum computing and its potential threat to cybersecurity. Our expert, Ellie, explains how quantum computing poses a challenge to our classical cryptography infrastructure, specifically relating to the RSA algorithm and elliptic curve cryptography. These algorithms can be efficiently broken by a quantum computer, jeopardizing the security of the public key cryptography layer that is essential for data encryption.

But how concerned should we be? Ellie breaks it down by discussing the concept of ‘harvest now, decrypt later’ and how the lifespan of data confidentiality plays a role in assessing the risk. Whether you use the internet for short-term or long-term sensitive data, the longer it needs to stay confidential, the higher the risk becomes.

So, what can we do about it? Cryptographic modernization is the term that refers to the necessary upgrades and changes in our encryption methods. Currently, we heavily rely on RSA and elliptic curve cryptography with no backup plan. However, with the development of quantum computers, it’s crucial to transition to post-quantum cryptography. This involves changing the underlying mathematics and implementing flexible, agile encryption that can adapt to potential attacks and algorithm vulnerabilities.

Join us in this video as we explore the impact of quantum computing on cybersecurity and the importance of modernizing our cryptography infrastructure. Don’t miss out on vital information that can help protect your data in an evolving digital landscape.
