Introduction to Cryptography: Basic Concepts and Techniques

WebIn this lesson, we introduce the basic term and concept of cryptography, which shows the mathematic formula and representation of cryptosystem and present you a encryption model or process, and two basic encryption method. Cryptography is a Greek word for, "Secret writing". There are two confusing terms in cryptography. WebTraditionally, cryptographic primitives are designed to protect data and keys against black-box attacks. In such a context, an adversary has knowledge of the algorithm ( Kerckhoffs’ Principle ) and may examine various inputs to and outputs from the system, but has no access to the internal details of the execution of a key instantiated primitive. WebJul 18, 2012 · In this article, we will try to learn the basics of cryptography. The Basic Principles 1. Encryption In a simplest form, encryption is to convert the data in some unreadable form.

WebThe term “cryptosystem” is shorthand for “cryptographic system” and refers to a computer system that employs cryptography, a method of protecting information and communications through the use of codes so that only those for whom the information is intended can read and process it. WebLightweight cryptography strikes an equal balance for the use of computational power and security. It helps to secure these devices against various attacks, such as single-key, key-recovery, or weak-keys.
