We explore the use of some combinatorial designs for possible use as secret codes. We are motivated to use designs as (1) combinatorial designs are often hard to find, (2) the algorithms for encryption ond decryption are of reasonable length, (3) combinatorial designs have very large numbers of designs in each equivalence class lending themselves readily to selection using a secret key.
