Usuba provides high-level abstractions tailored specifically for cryptographic primitives: lookup tables, permutation tables, functions, loops, multi-dimensional arrays...
Bitsliced (and msliced) codes have by nature an execution time independent of their inputs, thus making them immune to timing attacks. Furthermore, Usuba can automatically insert countermeasures (higher-order boolean masking) against power-based side-channel attacks.
Usuba is the fruit of a meticulous research which has been validated by the publication of several peer-reviewed articles:
The creators of USUBA regularly publish blog posts to help the community better understand how USUBA works. In particular, you can expect posts about bitslicing, compilation, and more!Read our blog
USUBA is an open-source project. We publish our code on Github, and you are most welcome to visit our repository there.Go to Github
A question without answer? A remark, comment on the project? An idea to improve USUBA or implement it to build new applications? We would be glad to hear about you.
