Cryptography Ppt Computer System Security Ppt Ppt This document provides an overview of cryptography. it defines cryptography as the science of securing messages from attacks. it discusses basic cryptography terms like plain text, cipher text, encryption, decryption, and keys. it describes symmetric key cryptography, where the same key is used for encryption and decryption, and asymmetric key cryptography, which uses different public and. Also known as secret key cryptography or conventional cryptography, symmetric key cryptography is an encryption system in which the sender and receiver of a message share a single, common key that is used to encrypt and decrypt the message.
