Design And Implementation Of A Versatile Hardware Crypto Ip For Symmetric And Asymmetric Algorithms

Abstract

This thesis includes six chapters. Chapter 1 contains a brief introduction in cryptography, a detailed description of the implemented symmetric-key and public-key algorithms, as well as references in each one’s applications in the daily life. In the second chapter the overall architecture of the Crypto IP is described: the main circuits implementing the cryptographic algorithms and a communication interface with the widely used AMBA bus so that the IP can be connected to a System on Chip. In chapters 3, 4 and 5 there is a detailed description of the implementation of each cryptographic circuit as well as a reference to the parameters which can be configured by the user. In chapter 6 there is a brief reference in the way that the functionality of these circuits was verified on an FPGA board using an external controller which feeds the circuits with the proper test cases. This thesis ends with an Appendix where the basic tables used by DES and AES algorithm are mentioned.
