As a seasoned cybersecurity analyst with over two decades of experience under my belt, I’ve witnessed the evolution of cryptography from its infancy to the complex systems we have today. The proposal by NIST to standardize the block and key size used in AES to 256 bits is a significant step towards future-proofing our digital infrastructure against the looming threat of quantum computers.
In simple terms, the National Institute of Standards and Technology (NIST) has suggested that we should all use a 256-bit block and key size when encrypting data with the Advanced Encryption Standard (AES).
As an analyst, I’m advocating for the expansion of block size based on the expanding needs of various data-heavy applications we’re seeing, along with the escalating demand for such data-intensive services.
At the moment, the AES (Advanced Encryption Standard) uses a 128-bit block size, and this standard supports three different key lengths: 128 bits, 192 bits, or 256 bits.
Strengthening the length of encryption keys can ensure quantum safety within a cryptographic system. If the encryption key length surpasses the number of digits a quantum computer can factor and crack, then the cryptographic protection remains intact.
Plans to develop quantum-resistant cryptography emerge
The potential danger of quantum computers deciphering current encryption methods employed in finance, digital currencies, and military communications became more apparent following Google’s unveiling of their Willow quantum processor.
It’s said that Willow has the ability to solve complex computational issues in just five minutes, which would take a computer using binary processing approximately 10 septillion years to figure out.
Although quantum computers boast an incredible surge in processing capabilities, they are held back by certain architectural constraints. One such limitation is the allocation of qubits for error correction, which currently makes it impossible for these devices to breach contemporary encryption codes.
In a blog post published on October 29th, Ethereum’s co-creator, Vitalik Buterin, proposed a strategy to make Ethereum resistant to quantum computing attacks through the use of account abstraction as part of its future development plans.
As per Buterin’s views, while it’s crucial that crypto networks gear up for the advent of quantum supremacy, the realistic threat quantum computers pose to encryption is not expected for several decades.
In November, the Singapore Monetary Authority (MAS) and Banque de France (BDF) concluded a trial on post-quantum cryptography. This test aimed to secure Microsoft Outlook emails using post-quantum computation for digital signature purposes.
Quantum-safe methods that offer protection against potential quantum attacks have been suggested as alternatives for systems using Elliptic Curve Digital Signature Algorithms (ECDSA). In simpler terms, these new techniques are proposed to ensure quantum security in systems where ECDSA is currently employed.
In contrast, Adam Back, co-founder and CEO of Blockstream, has expressed that it’s unlikely such hash-based methods will be employed, and he anticipates that post-quantum research will persist for the years leading up to quantum dominance.
