    en.wikipedia.org/wiki/Glossary_of_cryptographic_keys

    See traffic encryption key. symmetric key - a key that is used both to encrypt and decrypt a message. Symmetric keys are typically used with a cipher and must be kept secret to maintain confidentiality. traffic encryption key (TEK)/data encryption key (DEK) - a symmetric key that is used to encrypt messages. TEKs are typically changed ...

  3. Key escrow - Wikipedia

    en.wikipedia.org/wiki/Key_escrow

    Key escrow (also known as a "fair" cryptosystem) [1] is an arrangement in which the keys needed to decrypt encrypted data are held in escrow so that, under certain circumstances, an authorized third party may gain access to those keys.

  4. Cipher - Wikipedia

    en.wikipedia.org/wiki/Cipher

    Edward Larsson's rune cipher resembling that found on the Kensington Runestone.Also includes runically unrelated blackletter writing style and pigpen cipher.. In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.

    en.wikipedia.org/wiki/Résumé

    A résumé or resume (or alternatively resumé), [a] [1] is a document created and used by a person to present their background, skills, and accomplishments. Résumés can be used for a variety of reasons, but most often are used to secure new jobs, whether in the same organization or another.

  6. Cryptography - Wikipedia

    en.wikipedia.org/wiki/Cryptography

    Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message).

    en.wikipedia.org/wiki/Cryptosystem

    Mathematically, a cryptosystem or encryption scheme can be defined as a tuple (,,,,) with the following properties.. is a set called the "plaintext space". Its elements are called plaintexts.; is a set called the "ciphertext space". Its elements are called ciphertexts.; is a set called the "key space". Its elements are called keys.; = {:} is a set of functions :. Its elements are called ...

  8. Crypto-shredding - Wikipedia

    en.wikipedia.org/wiki/Crypto-shredding

    Crypto-shredding or crypto erase (cryptographic erasure) is the practice of rendering encrypted data unusable by deliberately deleting or overwriting the encryption keys: assuming the key is not later recovered and the encryption is not broken, the data should become irrecoverable, effectively permanently deleted or "shredded". [1]

  9. Key (cryptography) - Wikipedia

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

    Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained. A key's security strength is dependent on its algorithm, the size of the key, the generation of the key, and the process of key exchange.
