According to Cointelegraph, the U.S. National Institute of Standards and Technology (NIST) has proposed standardizing the block and key size of the Advanced Encryption Standard (AES) to 256 bits. NIST stated that the increase in block size is due to the growing number of applications that need to handle larger amounts of data, as well as the rising demand for these data-intensive applications. Currently, the block size used in AES is 128 bits, and the key lengths can be 128 bits, 192 bits, or 256 bits. Increasing the key length can provide quantum security for encryption systems. Google's Willow quantum processor has raised concerns about quantum computers potentially breaking modern encryption standards. Although the processing power of quantum computers has significantly increased, their design limitations still exist. Ethereum co-founder Vitalik Buterin proposed a plan to quantum-proof Ethereum through account abstraction in his blog. He believes that the actual threat of quantum computers to encryption will take decades to materialize. The Monetary Authority of Singapore and the Bank of France have completed post-quantum encryption tests, which tested the digital signatures of Microsoft Outlook emails protected by post-quantum computing. Blockstream co-founder and CEO Adam Back stated that hash-based quantum-resistant schemes may not be adopted, but post-quantum research will continue to develop before quantum supremacy arrives.
