TAILIEUCHUNG - Lecture Data security and encryption - Lecture 1: Introduction to Data Security and Encryption

This chapter presents the following content: Outline of the course is discussed; topic roadmap & standards organizations; security concepts; security architecture; security attacks, services, mechanisms; models for network (access) security. | Data Security and Encryption (CSE348) Lecture slides by Lawrie Brown for “Cryptography and Network Security”, 5/e, by William Stallings, briefly reviewing the text outline from Ch 0, and then presenting the content from Chapter 1 – “Introduction”. Dr. Basit Raza Assistant Professor Comsats Institute of Information Technology, Islamabad My name is Dr. Basit Raza and I am working as Assistant Professor in Comsats Institute of Information Technology, Islamabad. I have PhD in Computer Science. My area of specialization is all about data related such as Database, Data Management and Data warehouse. I have done My MS and PhD in Computer Science. Course Outline In this course we will follow the mentioned book Cryptography and Network Security”, 5th Edition by William Stallings. The book is organized into seven parts: Course Outline Part One: Symmetric Ciphers: Provides a survey of symmetric encryption, including classical and modern algorithms. The emphasis is on the two most important algorithms, the Data Encryption Standard (DES) and the Advanced Encryption Standard (AES).This part also covers the most important stream encryption algorithm,RC4,and the important topic of pseudorandom number generation. Course Outline Part Two: Asymmetric Ciphers: Provides a survey of public-key algorithms, including RSA (Rivest-Shamir-Adelman) and elliptic curve. Course Outline Part Three: Cryptographic Data Integrity Algorithms: Begins with a survey of cryptographic hash functions. This part then covers two approaches to data integrity that rely on cryptographic hash functions: message authentication codes and digital signatures. Course Outline Part Four: Mutual Trust: Covers key management and key distribution topics and then covers user authentication techniques. Course Outline Part Five: Network Security and Internet Security: Examines the use of cryptographic algorithms and security protocols to provide security over networks
