A simple substitution cipher where letters are shifted a fixed number of positions. Substitution Cipher: Replacing characters with others. Transposition Cipher: Rearranging the order of characters. 3. Modern Cryptographic Algorithms (Block Ciphers)

: Definitions and distinctions between Viruses, Worms, Trojan Horses, and Ransomware.

Prevents the sender from denying they sent the message. 5. Network Security Protocols and Practices cryptography and network security atul kahate ppt

There are two main types of cryptography: symmetric key cryptography and asymmetric key cryptography. Symmetric key cryptography uses the same secret key for both encryption and decryption, whereas asymmetric key cryptography uses a pair of keys: a public key for encryption and a private key for decryption. Hash functions are another type of cryptography that is used to ensure data integrity.

Presentations on cryptography rely heavily on visual aids to explain complex math and data flows. Ensure your PPT includes diagrams for the following processes: Show Plaintext →right arrow Encryption Algorithm (using Secret Key) →right arrow Ciphertext →right arrow Decryption Algorithm (using same Secret Key) →right arrow Original Plaintext.

: Ensuring systems and data are available to users when needed.

A method for two parties to agree on a secret key over an insecure channel. 5. Message Authentication and Hash Functions underlying mathematical principles

The book moves systematically from classical to modern, and symmetric to asymmetric systems.

is a definitive foundational textbook used globally by computer science and information technology students to master core cybersecurity concepts. Finding, creating, or using a presentation (PPT) based on this text requires a structured breakdown of its core chapters, underlying mathematical principles, and practical network defenses.
