In Theorem 6.1 of [3] it was shown that, when v = r + c - 1, every triple array TA(v, k, rr, cc, k : r ? c) is a balanced grid BG(v, k, k : r?c). Here we prove the converse of thi...

We present a family of hyperelliptic curves whose Jacobians are suitable for cryptographic use, and whose parameters can be specified in a highly efficient way. This is done via co...
