In this paper, we show that crossed-inverse quasigroups have certain properties which make them particularly appropriate for use in cryptography. In particular, we provide a construction forâ€¦ (More)

In an earlier paper, we showed that CI-loops and quasigroups with long inverse cycles have certain properties which make them particularly appropriate for use in cryptography. The same is true of theâ€¦ (More)

We prove that complete sets of orthogonal diagonal Sudoku latin squares (sometimes called Sudoku frames) exist of all orders p, where p is a prime. We also show that complete sets of orthogonalâ€¦ (More)
