2. Cryptography - Wikipedia

   en.wikipedia.org/wiki/Cryptography

   Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. [4] Core concepts related to information security ( data confidentiality , data integrity , authentication , and non-repudiation ) are also central to ...

3. Kerckhoffs's principle - Wikipedia

   en.wikipedia.org/wiki/Kerckhoffs's_principle

   A generalization some make from Kerckhoffs's principle is: "The fewer and simpler the secrets that one must keep to ensure system security, the easier it is to maintain system security." Bruce Schneier ties it in with a belief that all security systems must be designed to fail as gracefully as possible:

4. Salt (cryptography) - Wikipedia

   en.wikipedia.org/wiki/Salt_(cryptography)

   In cryptography, a salt is random data fed as an additional input to a one-way function that hashes data, a password or passphrase. [1] Salting helps defend against attacks that use precomputed tables (e.g. rainbow tables), by vastly growing the size of table needed for a successful attack.

5. Outline of cryptography - Wikipedia

   en.wikipedia.org/wiki/Outline_of_cryptography

   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 ...

6. Cryptographic protocol - Wikipedia

   en.wikipedia.org/wiki/Cryptographic_protocol

   For example, Transport Layer Security (TLS) is a cryptographic protocol that is used to secure web connections. [2] It has an entity authentication mechanism, based on the X.509 system; a key setup phase, where a symmetric encryption key is formed by employing public-key cryptography; and an application-level data transport function. These ...

7. Public-key cryptography - Wikipedia

   en.wikipedia.org/wiki/Public-key_cryptography

   The security of the system depends on the secrecy of the private key, which must not become known to any other. Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key.
