Enumeration of irreducible and extended irreducible Goppa codes

Kondwani Magamba, John A. Ryan

We obtain upper bounds on the number of irreducible and extended irreducible Goppa codes over $GF (p)$ of length $q$ and $q + 1$ , respectively defined by polynomials of degree $r$ , wh…

Counting Extended Irreducible Goppa Codes

Kondwani Magamba, John A. Ryan

We obtain an upper bound on the number of extended irreducible q-ary Goppa codes of degree $r$ and length $q^{n} + 1$ , where $q = p^{t}$ and $n$ and $r > 2$ are prime numbers.

Variable-length Hill Cipher with MDS Key Matrix

Kondwani Magamba, Solomon Kadaleka, Ansley Kasambara

The Hill Cipher is a classical symmetric cipher which breaks plaintext into blocks of size m and then multiplies each block by an m by m key matrix to yield ciphertext. However, it…
