Contrary to popular superstition, AES 128 is just fine in a post
With growing focus on the existential threat quantum computing poses to some of the most crucial and widely used forms of encryption, cryptography engineer Filippo Valsorda wants to make one thing absolutely clear: Contrary to popular mythology that refuses to die, AES 128 is perfectly fine in a post-quantum world. AES 128 is the most widely used variety of the Advanced Encryption Standard, a block cipher suite formally adopted by NIST in 2001. …
A new technical analysis argues that quantum computing does require replacing several asymmetric cryptography tools, but does not practically threaten AES-128 or SHA-256. The conclusion, supported by NIST, BSI and area specialists, points out that the post-quantity transition should focus on where the risk really lies. *** The article argues that AES-128 and SHA-256 remain safe against realistic quantum attacks. Grover’s theoretical acceleration…
