Cryptography And Network Security Atul Kahate Ppt Fix

Introduction

1. SSL/TLS (Secure Sockets Layer/Transport Layer Security): Provide end-to-end encryption for web traffic.
2. PGP (Pretty Good Privacy): Use symmetric key cryptography and digital signatures to secure email communications.
3. IPSec (Internet Protocol Security): Provide end-to-end encryption and authentication for IP traffic.

In today's digital age, the security of online transactions and communication has become a major concern. With the rapid growth of the internet and mobile devices, the risk of cyber attacks and data breaches has increased exponentially. Cryptography and network security are two essential components that work together to protect the confidentiality, integrity, and authenticity of data exchanged over the internet. In this essay, we will discuss the fundamental concepts of cryptography and network security, their importance, and the various techniques used to secure online communication. cryptography and network security atul kahate ppt
