Abstract
This paper presents the mapping and performance analysis of the Twofish algorithm on MorphoSys. MorphoSys is a reconfigurable architecture that can provide high performance compared to custom hardware and yet preserves a level of flexibility compared to general-purpose processors. With today’s high demand for secure data transfer mediums including wired and wireless networks, there is a growing demand for real-time implementation of cryptographic algorithms. The choice of the Twofish algorithm, one of the five AES finalists, is because it is computationally intensive algorithm. It requires lookup tables, logical and arithmetic computations that stipulate high flexibility and performance. So it is a perfect algorithm to be mapped in order to evaluate such hardware.
