We introduce QARMAvii, a redesign of the tweakable block cipher QARMA to provide more robust security bounds and allow for longer tweaks,

The longer tweaks serve to address specific use cases and facilitate the design of modes of operation with higher security bounds.
This is achieved by adopting new key …
