  2. Advanced Encryption Standard - Wikipedia

    en.wikipedia.org/wiki/Advanced_Encryption_Standard

    The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data. In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001.

  3. Ankh - Wikipedia

    en.wikipedia.org/wiki/Ankh

    The ankh or key of life is an ancient Egyptian hieroglyphic symbol used to represent the word for "life" and, by extension, as a symbol of life itself. The ankh has a T-shape topped by a droplet-shaped loop. It was used in writing as a triliteral sign, representing a sequence of three consonants, Ꜥ-n-ḫ. This sequence was found in several ...

  4. Computer keyboard - Wikipedia

    en.wikipedia.org/wiki/Computer_keyboard

    History. Typewriters are the definitive ancestor of all key-based text entry devices, but the computer keyboard as a device for electromechanical data entry and communication largely comes from the utility of two devices: teleprinters (or teletypes) and keypunches. It was through such devices that modern computer keyboards inherited their layouts.

  5. Identification key - Wikipedia

    en.wikipedia.org/wiki/Identification_key

    In biology, an identification key, taxonomic key, or biological key is a printed or computer-aided device that aids the identification of biological entities, such as plants, animals, fossils, microorganisms, and pollen grains.

  6. Passphrase - Wikipedia

    en.wikipedia.org/wiki/Passphrase

    NIST has estimated that the 23-character passphrase "IamtheCapitanofthePina4" contains a 45-bit strength. The equation employed here is: [4] 4 bits (1st character) + 14 bits (characters 2–8) + 18 bits (characters 9–20) + 3 bits (characters 21–23) + 6 bits (bonus for upper case, lower case, and alphanumeric) = 45 bits.

  7. Hardware security module - Wikipedia

    en.wikipedia.org/wiki/Hardware_security_module

    An internal HSM in PCIe format. A hardware security module ( HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys ), performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [1] These modules traditionally come in the form of a ...

  8. Multiple choice - Wikipedia

    en.wikipedia.org/wiki/Multiple_choice

    Multiple choice items consist of a stem and several alternative answers. The stem is the opening—a problem to be solved, a question asked, or an incomplete statement to be completed. The options are the possible answers that the examinee can choose from, with the correct answer called the key and the incorrect answers called distractors.

  9. Ciphertext - Wikipedia

    en.wikipedia.org/wiki/Ciphertext

    Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking. Decryption, the inverse of encryption, is the process of turning ciphertext into ...

  10. Terminology - Wikipedia

    en.wikipedia.org/wiki/Terminology

    Terminology science is a branch of linguistics studying special vocabulary. The main objects of terminological studies are special lexical units (or special lexemes ), first of all terms. They are analysed from the point of view of their origin, formal structure, their meanings and also functional features. Terms are used to denote concepts ...

    en.wikipedia.org/wiki/Cryptography

    Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized : kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively [1] ), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
