Checksum is a method of checking for errors in a communications system. I'm Mr. Woo and my channel is all about learning - I love doing it, and I love helping others to do it too. I guess that's why I became a teacher! I hope you get something out of these videos - I upload almost every weekday, so subscribe to find out when there's something new!

This is a short vid which shows the code for the matrix multiplication for the MixColumns step. I initially intended to make this vid and the previous AES one around the same length, but we actually covered almost everything in the previous vid! Mix Columns Wikipedia Page: https://en.wikipedia.org/wiki/Rijndael_mix_columns Code for dot products: tmp = (unsigned char)(mul2[state] ^ mul3[state] ^ state ^ state); tmp = (unsigned char)(state ^ mul2[state] ^ mul3[state] ^ state); tmp = (unsigned char)(state ^ state ^ mul2[state] ^ mul3[state]); tmp = (unsigned char)(mul3[state] ^ state ^ state ^ mul2[state]); tmp = (unsigned char)(mul2[state] ^ mul3[state] ^ state ^ state); tmp = (unsigned char)(state ^ mul2[state] ^ mul3[state] ^ state); tmp = (unsigned char)(state ^ state ^ mul2[state] ^ mul3[state]); tmp = (unsigned char)(mul3[state] ^ state ^ state ^ mul2[state]); tmp = (unsigned char)(mul2[state] ^ mul3[state] ^ state ^ state); tmp = (unsigned char)(state ^ mul2[state] ^ mul3[state] ^ state); tmp = (unsigned char)(state ^ state ^ mul2[state] ^ mul3[state]); tmp = (unsigned char)(mul3[state] ^ state ^ state ^ mul2[state]); tmp = (unsigned char)(mul2[state] ^ mul3[state] ^ state ^ state); tmp = (unsigned char)(state ^ mul2[state] ^ mul3[state] ^ state); tmp = (unsigned char)(state ^ state ^ mul2[state] ^ mul3[state]); tmp = (unsigned char)(mul3[state] ^ state ^ state ^ mul2[state]); Music Channel: Sober: https://youtu.be/Y2LCg3cGu7U Gold Digger: https://youtu.be/wAoXB8tg0co Become a patron and support What's a Creel programming vids on Patreon: www.patreon.com/whatsacreel FaceBook: www.facebook.com/pages/WhatsaCreel/167732956665435

IMPORTANT AND STANDARD BOOKS FOR GATE EXAMINATION: ====================================================== Discrete Mathematics and Its Applications ***** Kenneth H. Rosen Computer Architecture - A Quantitative Approach ***** Hennessey, Patterson Computer Organisation ***** Hamacher Computer Networks ***** Tanenbaum,Andrew Tanenbaum Data Communications and Networking ***** Behrouz A.Forouzan Compiler Design ***** Aho Ullman Sethi Programming in C language ***** Kernighan Ritchie Introduction to Algorithms ***** Cormen Leiserson Rivest and Stein - MIT Press Data Structures and Algorithm Analysis in C ***** Mark Allen Weiss Database System Concepts ***** Korth Fundamentals of Database Systems ***** Navathe Computer Organization and Architecture ***** William Stallings Computer System Architecture ***** Moris Mano Operating System Concepts ***** Silberschatz Galvin Introduction to Formal Languages and Automata ***** PETER LINZ Introduction to the Theory of Computation ***** MICHAEL SIPSER Massachusetts 1. An Introduction to Formal Languages and Automata by Peter Linz. This is the best book for GATE as far as TOC is concerned. It covers all the topics with lucid explanation and interesting problems at the end of each chapter. If one goes through this book nicely, it will help you to score full marks in TOC. 2. Discrete Mathematics and Its Applications by Kenneth Rosen. This is the perfect book for Introductory Discrete Mathematics, highly recommended for GATE. This book is a must read for any computer scientist. It will help you build a solid foundation in combinatorics, graph theory which carries over through Algorithms as well. Especially the first chapter on propositional logic is intriguing. 3. Introduction to Algorithms (C.L.R.S) If computer science is religion, this book is Gita/Kuran/Bible. The Art of Computer Programming, by Donald E. Knuth (Volumes 1-4) are Vedas. CLRS is necessary and sufficient for GATE. Ideally one should implement the algorithms in C/C++. 4. Database Systems by Elmasri, Navathe It is an excellent book for GATE. You can depend on this book for the entire syllabus. In addition, you can refer Database Management Systems by Raghu Ramakrishnan for transaction management. 5. Computer System Architecture by Morris Mano This book will clear your basics and you should be able to solve previous GATE questions with ease. In addition, for pipelining Computer Organization by HAMACHER can be referred. 6. The C Programming Language by Dennis Ritchie Just Stick with this book for C Programming Language. 7. Data Communications and Networking by Forouzan This is a comprehensive book for a vast subject and can be referred to clear networking concepts. Computer Networking by James F. Kurose is quite popular among GATE aspirants. 8. Operating System Concepts by Galvin This is a very interesting book, covering entire GATE syllabus and easy to understand. 9. Data Structures Using C by Tenenbaum A solid grasp on data structures is very important for a good programmer and this book is a great one to start with & Sufficient for GATE. 10. Compilers: Principles, Techniques, & Tools by Ullman This is perhaps the only book where examples are given excellently. It will help you to understand the compiler concepts well. 11. Modern Digital Electronics by R.P Jain This is a very good book for digital and can be read along with NPTEL lecture by Prof.S.Srinivasan. Digital Logic and Computer Design by M. Morris Mano is an excellent book.
