It is a cryptographic algorithm that takes a ciphertext and a decryption key as input, and outputs a plaintext. It can be intercepted or compromised by anyone who has access to the communication channel.ĭecryption Algorithm, It is a mathematical process, that produces a unique plaintext for any given ciphertext and decryption key. It is the scrambled version of the plaintext produced by the encryption algorithm using a specific the encryption key. It is a cryptographic algorithm that takes plaintext and an encryption key as input and produces a ciphertext.Ĭiphertext. It is a mathematical process that produces a ciphertext for any given plaintext and encryption key. It is the data to be protected during transmission.Įncryption Algorithm. The various components of a basic cryptosystem are as follows − The objective of this simple cryptosystem is that at the end of the process, only the sender and the receiver will know the plaintext. The illustration shows a sender who wants to transfer some sensitive data to a receiver in such a way that any party intercepting or eavesdropping on the communication channel cannot extract the data. This basic model is depicted in the illustration Let us discuss a simple model of a cryptosystem that provides confidentiality to the information being transmitted. A cryptosystem is also referred to as a cipher system. A cryptosystem is an implementation of cryptographic techniques and their accompanying infrastructure to provide information security services.
