Capillaries and the Electroosmotic Flow,Trapdoor Functions and encryption schemes with improved security, like Key Dependent Message resilience. In these constructions the rank of a matrix is assumed to be hard to guess when the matrix is hidden by elementwise exponentiation. This problem, that we call here the Rank Problem, is known to b

Much of this work has focused on the characterization of trivial and complete functionalities (resp., functionalities that can be securely implemente

Our cipher, named ., allows encryption of data within one clock cycle with a very competitive chip area compared to known solutions. The fully unrolled fashion in which such algorithms need to be implemented calls for innovative design choices. T

Reinhard Kuhn,Sabrina Hoffstetter-Kuhnoduce new multi-bit constraints to describe differential characteristics in ARX designs more accurately, and quartet constraints to analyze boomerang attacks. We also describe how to propagate those constraints; this can be used either to assist manual construction of a differential characteristic,
