Discuss. In cryptography, the avalanche effect is a term associated with a specific behavior of mathematical functions used for encryption. Avalanche effect is considered as one of the desirable property of any encryption algorithm. A slight change in either the key or the plain-text should result in a significant change in the cipher-text.

A cryptosystem is an implementation of cryptographic techniques and their accompanying infrastructure to provide information security services. A cryptosystem is also referred to as a cipher system. Let us discuss a simple model of a cryptosystem that provides confidentiality to the information … See more The various components of a basic cryptosystem are as follows − 1. Plaintext.It is the data to be protected during transmission. 2. Encryption Algorithm.It is a … See more Fundamentally, there are two types of cryptosystems based on the manner in which encryption-decryption is carried out in the system − 1. Symmetric Key Encryption 2. … See more In the 19thcentury, a Dutch cryptographer A. Kerckhoff furnished the requirements of a good cryptosystem. Kerckhoff stated that a cryptographic system should be secure even if everything … See more A summary of basic key properties of two types of cryptosystems is given below − Due to the advantages and disadvantage of both the systems, … See more http://staffnew.uny.ac.id/upload/198505132010122006/penelitian/full-paper-dwi-zakix.pdf WebThe simple XOR cipher, used in the early days of computers, can be also broken easily by knowing only some parts of plaintext and corresponding encrypted messages. Modern ciphers are generally resistant against purely known-plaintext attacks. One of the unfortunate exceptions was the old encryption method using in PKZIP application. howick community board
