Abstract: S-boxes are the only source of non-linearity in many symmet-ric primitives. While they are often defined as being functions operatingon a small space, some recent designs propose the use of much larger ones(e.g., 32 bits). In this context, an S-box is then defined as a subfunctionwhose cryptographic properties can be estimated precisely.We present a 64-bit ARX-based S-box calledAlzette, which can be eval-uated in constant time using only 12 instructions on modern CPUs. Itsparallel application can also leverage vector (SIMD) instructions. Oneite... (read more)

Topic-specific impact indicators

Popularity:
This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
Influence:
This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Citation Count:
This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Impulse:
This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network.
