NIST proposal: Development of a new AES mode that is a tweakable, variable–input–length strong pseudo-random permutation (VIL-SPRP) with a reduction proof to the security of the underlying block cipher.
Comments due: July 1, 2024
Next step: NIST will publish a draft NISTIR including Accordion design requirements.
