  3. Direct Anonymous Attestation - Wikipedia

    en.wikipedia.org/wiki/Direct_Anonymous_Attestation

    The solution first adopted by the TCG (TPM specification v1.1) required a trusted third-party, namely a privacy certificate authority (privacy CA). Each TPM has an embedded RSA key pair called an Endorsement Key (EK) which the privacy CA is assumed to know. In order to attest the TPM generates a second RSA key pair called an Attestation ...

  4. Name–value pair - Wikipedia

    en.wikipedia.org/wiki/Name–value_pair

    Example of a web form with name-value pairs. A name–value pair, also called an attribute–value pair, key–value pair, or field–value pair, is a fundamental data representation in computing systems and applications. Designers often desire an open-ended data structure that allows for future extension without modifying existing code or data.

  5. Tokenization (data security) - Wikipedia

    en.wikipedia.org/wiki/Tokenization_(data_security)

    Token Generation is the process of producing a token using any means, such as mathematically reversible cryptographic functions based on strong encryption algorithms and key management mechanisms, one-way nonreversible cryptographic functions (e.g., a hash function with strong, secret salt), or assignment via a randomly generated number.

  6. Byte pair encoding - Wikipedia

    en.wikipedia.org/wiki/Byte_pair_encoding

    The byte pair "aa" occurs most often, so it will be replaced by a byte that is not used in the data, such as "Z". Now there is the following data and replacement table: ZabdZabac Z=aa Then the process is repeated with byte pair "ab", replacing it with "Y": ZYdZYac Y=ab Z=aa

  7. Cryptographic key types - Wikipedia

    en.wikipedia.org/wiki/Cryptographic_key_types

    Key transport keys are usually used to establish keys (e.g., key wrapping keys, data encryption keys or MAC keys) and, optionally, other keying material (e.g., initialization vectors). Public key transport key Public key transport keys are the public keys of asymmetric key pairs that are used to encrypt keys using a public key algorithm.

  8. Digital Signature Algorithm - Wikipedia

    en.wikipedia.org/wiki/Digital_Signature_Algorithm

    The DSA works in the framework of public-key cryptosystems and is based on the algebraic properties of modular exponentiation, together with the discrete logarithm problem, which is considered to be computationally intractable. The algorithm uses a key pair consisting of a public key and a private key.

  9. Key Management Interoperability Protocol - Wikipedia

    en.wikipedia.org/wiki/Key_Management...

    Re-Key, Re-Key-Key-Pair: creating a new key that can replace an existing key. There are also attributes that can be used to have the server automatically rotate keys after a given period or number of uses. The Name is moved to the new key and is normally used to retrieve a key for protection operations such as encrypt and sign.
