Basic Cryptography And Network Security Pdf Cryptography Encryption Modern cryptography is built on four fundamental principles: 1. data confidentiality. confidentiality ensures that information is accessible only to authorized individuals or systems. it is usually enforced through encryption techniques and confidentiality agreements. 2. data integrity. This tutorial is meant for students of computer science who aspire to learn the basics of cryptography. it will be helpful for networking professionals as well who would like to incorporate various cryptographic algorithms to ensure secure data communication over their networks.
Chap1 Introduction Number Theory And Basic Cryptography Pdf Goal: the primary goal of cryptography is to secure important data on the hard disk or as it passes through a medium that may not be secure itself. usually, that medium is a computer network. The most common tool for providing network security is cryptography, an old technique that has been revived and adapted to network security. this book first introduces the reader to the principles of cryptography and then applies those principles to describe network security protocols. Cryptography and network security are interdependent. while cryptography provides tools and techniques for securing data in transit, network security provides an environment where cryptographic methods can effectively be deployed. Historically, cryptography was used for confidentiality: keeping messages secret encryption goes back thousands of years today, we do much more, including authentication, integrity checking, “signing” documents, playing games of chance over the internet, cryptocurrencies like bitcoin, etc.
