Network Security Cryptography Pdf Key Cryptography Public Key Cryptographic techniques: plain text and cipher text, substitution techniques, transposition techniques, encryption and decryption, symmetric and asymmetric key cryptography, steganography, key range and key size, possible types of attacks. Cryptography is technique of securing information and communications through use of codes so that only those person for whom the information is intended can understand it and process it. thus preventing unauthorized access to information.

Cryptography And Network Security Pdf Public Key Cryptography Key This document provides notes on cryptography and network security. it covers topics like key management, symmetric encryption, modern block ciphers like the data encryption standard (des), and modes of operation for block ciphers such as electronic codebook (ecb), cipher block chaining (cbc), cipher feedback (cfb), output feedback (ofb), and. Public key cryptography is also called asymmetric key cryptography and often involves a hashing function. ciphering engines are either block ciphers which encrypt blocks of text at a time, or stream ciphers, which produce an output bit stream in response to an input bit stream. Working principles and utilities of various cryptographic algorithms including secret key cryptography, hashes and message digests, and public key algorithms. Explores the basic issues to be addressed by a network security capability through a tutorial and survey of cryptography and network security technology. examines the practice of network security via practical applications that have been implemented and are in use today.

Explain the importance and application of each of confidentiality, integrity, authentication and availability and to understand various cryptographic algorithms. generate and distribute a pgp key pair and use the pgp package to send an encrypted e mail message. unit i. •to understand cryptography theories, algorithms and systems. •to understand necessary approaches and techniques to build protection mechanisms in order to secure computer networks. Cryptography provides key building block for many network security services. security services: . cryptographic algorithms (building blocks): encryption: symmetric encryption (e.g., aes), asymmetric encryption (e.g., rsa, el gamal) ! hashing functions. message authentication code (e.g., hmac sha1). While encryption is probably the most prominent example of a crypto graphic problem, modern cryptography is much more than that. in this class, we will learn about pseudorandom number generators, digital signatures, zero knowledge proofs, multi party computation, to name just a few examples.
