A Vlsi Architecture For Rijndael, The Advanced Encryption Standard, Naga M. Kosaraju

USF Tampa Graduate Theses and Dissertations

The increasing application of cryptographic algorithms to ensure secure communications across virtual networks has led to an ever-growing demand for high performance hardware implementations of the encryption/decryption methods. The inevitable inclusion of the cryptographic algorithms in network communications has led to the development of several encryption standards, one of the prominent ones among which, is the Rijndael, the Advanced Encryption Standard. Rijndael was chosen as the Advanced Encryption Standard (AES) by the National Institute of Standard and Technology (NIST), in October 2000, as a replacement for the Data Encryption Standard (DES). This thesis presents the architecture for the VLSI implementation …

Embedded Cryptography: An Analysis And Evaluation Of Performance And Code Optimization Techniques For Encryption And Decryption In Embedded Systems, Jayavardhan R. Kandi

USF Tampa Graduate Theses and Dissertations

It is clear that Cryptography is computationally intensive. It is also known that embedded systems have slow clock rates and less memory. The idea for this thesis was to study the possibilities for analysis of cryptography on embedded systems. The basic approach was the implementation of cryptographic algorithms on high-end, state-of-the-art, DSP chips in order to study the various parameters that optimize the performance of the chip while keeping the overhead of encryption and decryption to a minimum.

Embedded systems are very resource sensitive. An embedded system is composed of different components, which are implemented in both hardware and software. …
