Encryption techniques

Lecture Cryptography: Modern Symmetric Ciphers (Part 1) focuses on classical symmetric cipher algorithms and introduces modern techniques. The lecture explores block ciphers, stream ciphers, and provides an in-depth analysis of the Data Encryption Standard (DES). This serves as a foundation for understanding advanced symmetric encryption. Please refer to the lecture for more details!

Lecture Cryptography: Modern Symmetric Ciphers (Part 2) delves into the Advanced Encryption Standard (AES) and modes of operation. The lecture explains how AES improves upon previous methods and introduces multiple techniques for secure encryption processing. It also examines how data can be handled in different cipher modes. Please refer to the lecture for more details!

This paper presents a flexible, highperformance implementation of the AES algorithm on a coarse-grained reconfigurable architecture, called MUSRA (Multimedia Specific Reconfigurable Architecture). First, we propose a hardware-software partitioning method for mapping the AES algorithm onto the MUSRA. Second, the parallel and pipelining techniques are considered thoughtfully to increase total computing throughput by efficiently utilizing the computing resources of the MUSRA.

In the last lecture we looked at some high-level descriptions of key distribution and agreement schemes. These protocols cannot be used as they were stated. In implementation of the actual protocol, there are many situations one should be careful of. In this lecture, we will look at some common protocol failures that arise when trying to implement security protocols We will then look at some specific examples of security protocols
