Kerckhoffs viewed cryptography as a rival to, and a better alternative than, steganographic encoding, which was common in the nineteenth century for hiding the meaning of military messages. One problem with encoding schemes is that they rely on humanly-held secrets such as "dictionaries" which disclose for example, the secret meaning of words.
Historically, various forms of encryption have been used to aid in cryptography. Early encryption techniques were often used in military messaging. Since then, new techniques have emerged and become commonplace in all areas of modern computing. [1] Modern encryption schemes use the concepts of public-key and symmetric-key. [1]
The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem.
The public developments of the 1970s broke the near monopoly on high quality cryptography held by government organizations (see S Levy's Crypto for a journalistic account of some of the policy controversy of the time in the US). For the first time ever, those outside government organizations had access to cryptography not readily breakable by ...
It is one of the foundational treatments (arguably the foundational treatment) of modern cryptography. [2] His work has been described as a "turning point, and marked the closure of classical cryptography and the beginning of modern cryptography." [3] It has also been described as turning cryptography from an "art to a science". [4]
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. The two main goals of the study are definitions and proofs of security.
The following outline is provided as an overview of and topical guide to cryptography: Cryptography (or cryptology) – practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Applications of cryptography include ATM cards, computer passwords, and electronic ...
