    The HRF Model Built on Dynamic High-Order Hill Matrix-Keys and the Rail Fence Model
    Author(s): Colin Chibaya*

    The Hill model is a compelling asymmetric algorithm which depends on matrices as keys to achieve data security. Research done on the Hill model, often, restricted to the use of low order matrix keys because of the complexity of operations with high order matrices. This, however, expose the Hill model to basic brute force attacks. This article investigates the use of high order dynamically generated matrix keys selected at run-time. In addition, the original Hill model only uses the 26 alphabetic characters. We extend the character set supported by the Hill model to the 256 ASCII characters. On the other hand, the rail fence model is also a compelling transposition algorithm which generally supports a low character set. This article investigates the combination of the improved Hill model with the rail fence model towards a hybrid product Hill-Rail Fence (HRF) model. Ideally, product ci.. View more»
