Cryptography And Network Security Atul Kahate Ppt <CERTIFIED>

Obscuring the relationship between the plaintext/key and the ciphertext (achieved via substitution).

An older block cipher that laid the foundation for modern security.

A hash function takes an input of arbitrary length and produces a fixed-size output (digest). It must be:

Rail Fence Cipher, Row Transposition.

An interim adaptation that applies DES three times with up to three different keys, extending the effective key length to improve brute-force resistance. cryptography and network security atul kahate ppt

: Ensuring only authorized users can access information.

: Types of firewalls including Packet Filters, Stateful Inspection Firewalls, and Application-Level Gateways.

SSL/TLS protocols and Secure Electronic Transaction (SET).

Maintaining Confidentiality (encryption), Integrity (hashing), and Availability (uptime). Obscuring the relationship between the plaintext/key and the

This article outlines the key topics typically covered in a presentation based on Kahate's curriculum, from basic principles to advanced real-world applications. 1. Fundamentals of Security

Malicious software (viruses, worms, Trojan horses) and Firewalls. 2. Key Diagrams to Include in Your Slides

) derived from their own private secrets. An eavesdropper watching the network traffic sees the public components but cannot compute the shared secret key

A PPT based on Atul Kahate’s work transforms these advantages into bullet points, diagrams, and flowcharts—ideal for last-minute revision before a semester exam. It must be: Rail Fence Cipher, Row Transposition

Symmetric key cryptography is the oldest and fastest form of encryption. Kahate’s literature breaks this down into two distinct categories: classical ciphers and modern symmetric algorithms. Classical Substitution and Transposition Ciphers

Ensuring that systems, networks, and data are accessible to authorized users whenever needed, resisting Denial of Service (DoS) attacks.
