  2. Associative containers (C++) - Wikipedia

    en.wikipedia.org/wiki/Associative_containers_(C++)

    A map, sometimes referred to as a dictionary, consists of a key/value pair. The key is used to order the sequence, and the value is somehow associated with that key. For example, a map might contain keys representing every unique word in a text and values representing the number of times that word appears in the text.

  3. ElGamal signature scheme - Wikipedia

    en.wikipedia.org/wiki/ElGamal_signature_scheme

    The algorithm uses a key pair consisting of a public key and a private key. The private key is used to generate a digital signature for a message, and such a signature can be verified by using the signer's corresponding public key. The digital signature provides message authentication (the receiver can verify the origin of the message ...

  4. One-time pad - Wikipedia

    en.wikipedia.org/wiki/One-time_pad

    One way to implement this quantum one-time pad is by dividing the 2n bit key into n pairs of bits. To encrypt the state, for each pair of bits i in the key, one would apply an X gate to qubit i of the state if and only if the first bit of the pair is 1, and apply a Z gate to qubit i of the state if and only if the second bit of the pair is 1.

  5. Message authentication code - Wikipedia

    en.wikipedia.org/wiki/Message_authentication_code

    Formally, a message authentication code (MAC) system is a triple of efficient [4] algorithms (G, S, V) satisfying: G (key-generator) gives the key k on input 1 n, where n is the security parameter. S (signing) outputs a tag t on the key k and the input string x. V (verifying) outputs accepted or rejected on inputs: the key k, the string x and ...

    en.wikipedia.org/wiki/Standard_Template_Library

    Apache C++ Standard Library (The starting point for this library was the 2005 version of the Rogue Wave standard library [15]) Libstdc++ uses code derived from SGI STL for the algorithms and containers defined in C++03. Dinkum STL library by P.J. Plauger; The Microsoft STL which ships with Visual C++ is a licensed derivative of Dinkum's STL.

  7. Key derivation function - Wikipedia

    en.wikipedia.org/wiki/Key_derivation_function

    Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...

  8. Identity-based encryption - Wikipedia

    en.wikipedia.org/wiki/Identity-based_encryption

    Identity-based encryption (IBE), is an important primitive of identity-based cryptography.As such it is a type of public-key encryption in which the public key of a user is some unique information about the identity of the user (e.g. a user's email address).

  9. Key exchange - Wikipedia

    en.wikipedia.org/wiki/Key_exchange

    Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key.
