abstract={The need for simple secure substitution encryption algorithms has risen due to complexities derived from current encryption algorithms, which over-complicate the process through many sub-processes and consume more space than necessary. This also creates the need for a secure string encryption approach that can also be applied using a simple pen and paper to encrypt and decrypt messages between each other. In this paper we present a technique based on a Non-Deterministic directional <i>N</i>x<i>N</i> chart-based encryption cipher as a solution to this problem. This will be achieved by using a 2-dimensional <i>N</i> by <i>N</i> chart as the key while using a dynamically selected directional approach to generate both the cipher and plain-text.},
