How Quantum Computers Break The Internet... Starting Now - Veritasium

SNDL, or "Store Now Decrypt Later," refers to a type of encryption where data is stored in an encrypted format and decrypted later when it is needed. This technique is often used to protect sensitive data, such as passwords or credit card information, during storage and transmission.

By encrypting the data, it becomes much more difficult for unauthorized parties to access or steal it. When the data is needed, it can be decrypted using a key or password.

Quantum computers have the potential to break many current encryption methods, including some of the most widely used ones such as RSA and Elliptic Curve Cryptography (ECC). This is because quantum computers can use a technique called Shor's algorithm to factor large numbers much faster than classical computers.

However, it's important to note that quantum computers are still in their infancy and currently have limited practical applications. The technology is still being developed and it's unclear when or if quantum computers will become powerful enough to break encryption on a large scale.

That being said, researchers are actively working on developing new encryption methods that are resistant to attacks from quantum computers, such as post-quantum cryptography. Bob says:

Why it's important

Encryption is widely used for many different purposes, including:

Securing data transmission: Encryption is used to secure data transmission over the internet, such as when you use online banking or send sensitive information via email.

Protecting data at rest: Encryption is used to protect data that is stored on devices like computers, smartphones, and servers. This helps to prevent unauthorized access to the data in case the device is lost, stolen, or hacked.

Authentication: Encryption is used to authenticate users and devices, ensuring that only authorized parties can access certain data or systems.

Digital signatures: Encryption is used to create digital signatures, which provide a way to verify the authenticity and integrity of digital documents.

Secure communication: Encryption is used in many communication systems, such as secure messaging apps and virtual private networks (VPNs), to ensure that messages and data are secure and private.

Password storage: Encryption is used to securely store passwords and other sensitive information, such as credit card numbers, to prevent unauthorized access and theft.

TL;DR: encryption is a critical tool for protecting sensitive data and ensuring privacy and security in many different contexts. Quantum computers can break many of the current encryption methods used to protect sensitive data. This means that Q-AI (quantum artificial intelligence) could be used to hack into systems and steal confidential information.

They're considering mathematical approaches as a means to resist attacks. Such as the use of one-way functions, which are easy to compute in one direction but difficult to reverse.
