NIST PROPOSES STANDARDIZING A WIDER VARIANT OF AES ENCRYPTION

The National Institute of Standards and Technology (NIST) seeks public input on
the proposed changes until June 25, 2025.

The National Institute of Standards and Technology (NIST) recently proposed
standardizing the block and key size used in the Advanced Encryption Standard
(AES) to 256 bits.

According to NIST, increasing the block size is necessary due to the number of
applications with larger volumes of data to process and the growing demand for
these data-intensive applications.

Currently, the block size used in AES, which comes from the Rijndael block
cipher family, is 128 bits, with varying encryption key lengths of 128 bits, 192
bits, or 256 bits.

Increasing encryption key lengths can provide quantum security to a
cryptographic system. As long as the encryption key lengths are larger than the
number of bits a quantum computer can factor and break, cryptographic security
is preserved.

PLANS TO DEVELOP QUANTUM-RESISTANT CRYPTOGRAPHY EMERGE

The threat of quantum computers breaking modern encryption standards used in
banking, cryptocurrencies, and military intelligence came into sharper focus
after Google revealed its Willow quantum processor.

Willow can reportedly solve computational problems in five minutes that would
take a binary-based computer 10 septillion years to crack.

Despite the exponential increase in processing power, quantum computers have
design limitations, including the number of qubits dedicated to error correction
that prevent these systems from cracking modern encryption standards.

Ethereum co-founder Vitalik Buterin outlined a plan to quantum-proof Ethereum
using account abstraction as part of the network’s roadmap in an Oct. 29 blog
post.

According to Buterin, although crypto networks must prepare for quantum
supremacy, quantum computers posing meaningful risks to encryption are decades
away.

In November, the Singapore Monetary Authority (MAS) and Banque de France (BDF)
completed a post-quantum cryptography test. The experiment tested securing
Microsoft Outlook emails with post-quantum computing to digitally sign the
emails.

Hash-based, quantum-resistant solutions have also been proposed as a way to
provide quantum security for systems relying on elliptical curve digital
signature algorithms (ECDSA).

However, co-founder and CEO of Blockstream Adam Back recently wrote that
implementing these hash-based schemes would likely never be used and said that
post-quantum research would continue to develop in the decades preceding quantum
supremacy.
