This lesson consists of introduction to cryptography and the ways of cryptography in old times.

Introduction to Cryptography

In this lesson we will look to learn about the differences between modern day cryptography and old days of cryptography.

Evolution of Cryptography

This lesson covers the security services which cryptography offers when we implement it in our system.

Security Services of Cryptography

This lesson involves the fundamentals of cryptosystems and the types of cryptosystems in existence.

Beginning with Cryptosystems

This lesson covers the explanation for symmteric key encryption and features of it. Along with this, we also look at the challenges of it.

Understanding Symmetric Key Encryption

It's time to learn about asymmteric key encryption and the features of it. Also loom at how it has solved the challenge faced by it.

Understanding Asymmetric Key Encryption

In this lesson we discuss about the threats and attacks encountered in day to day life in the cryptosystems.

Threats and Attacks to Cryptosystems

What do you know about DoS Attacks? Let's learn about them and their types and how they damage the affected systems

DoS Attacks and its types

We will discuss Bandwidth attacks in which different types of attacks are known. Also we will understand the damages these attacks cause.

Understanding Bandwidth Attacks

We will cover the two remaining types of DoS attacks in this lesson and learn about them.

Understanding Protocol and Software Vulnerability Attacks

Let's look at how our ancestors use to perform encryption and decryption by looking at traditional ciphers.

Traditional Ciphers

Finally we will be looking at new age cryptographic techniques by learning about Block cipher which is the building block of numerous encryption schemes.

Block Cipher.

After having learned about Block Cipher, we will be learning about Feistel Cipher which is considered to be enhanced version of it.

Feistel Block Cipher

Now we will learn about Data Encryption Standard which is symmteric key encryption technique and is used widely because of its robust nature

Data Encryption Standard (DES)

Let's learn about the types of DES variants which were used for overcoming the weakness of DES.

Double and Triple DES

We will learn about an enhanced version of Advanced Encryption Standard which is the most widely used encryption algorithm in present day.

Advanced Encryption Standard (AES)

Even there are some ways of adding security to block cipher modes of operation. In this lesson we will look at that in depth.

Block Cipher Modes of Operation - 1

This will be the second part of Block Cipher modes of operation where the remaining types of modes of operation is discussed.

Block Cipher Modes of Operation - 2

In this lesson we will learn about the most preferred way of securing large networks from attacks by using Firewalls.

Introduction to Firewalls

Do you know the difference between crackers and hackers. Well we will learn about them in this lesson and also look to know about the types of hackers and hackers hacking methodology

Types of Hackers, their methodology and Foot printing.

Ayush Singhal

In this course, introduction to Cryptography, Security goals and Security attacks are covered.

I'm a Software Engineer experienced in domains like FinTech, AI & Data Science. I'm passionate about teaching and eager to learn new things.

Tripti Tanvi

There is a necessity to address the rising security concerns and issues. This course has been developed keeping in mind the industry demands and the opportunities for Information Security enthusiasts.
The course aims to help the students in understanding the concepts and symmetric cipher techniques in a simple and lucid manner.

Learning Symmetric Cryptography: The Easy Way!

The course introduces the various types of malicious software affecting the system, along with the countermeasures and recovery methods. Tripti Tanvi discusses about Viruses, Worms and Firewall System in depth.

Introduction to System Security

This course is an introduction to different types of Authentication Protocol used.

Introduction to Authentication Protocol

The course goes in depth about the use of public key in the encryption process. Key distribution and management has been explained in detail. Number Theory problems often asked are solved for the ease of viewers.
