Cryptography basics pdf

  • Basic cryptography techniques

    At its most basic level, encryption is the process of protecting information or data by using mathematical models to scramble it in such a way that only the parties who have the key to unscramble it can access it..

  • Components of cryptography

    Theory of cryptography refers to the study of cryptographic algorithms and protocols in a formal framework.
    The two main goals of the study are definitions and proofs of security..

  • What are the basic principles of cryptography?

    Data Confidentiality, Data Integrity, Authentication and Non-repudiation are core principles of modern-day cryptography.
    Confidentiality refers to certain rules and guidelines usually executed under confidentiality agreements which ensure that the information is restricted to certain people or places..

This guide includes the following chapters: • Chapter 1, The Basics of Cryptography, provides an overview of the terminology and concepts you will encounter as 
Relativistic quantum cryptography is a sub-field of quantum cryptography, in which in addition to exploiting the principles of quantum physics, the no-superluminal signalling principle of relativity theory stating that information cannot travel faster than light is exploited too.
Technically speaking, relativistic quantum cryptography is a sub-field of relativistic cryptography, in which cryptographic protocols exploit the no-superluminal signalling principle, independently of whether quantum properties are used or not.
However, in practice, the term relativistic quantum cryptography is used for relativistic cryptography too.
