?:definition
  • Security metadata observation value used to indicate the mechanism by which software systems can establish that data was not modified in transit.

    Rationale:This definition is intended to align with the ISO 22600-2 3.3.19 definition of cryptographic checkvalue: Information which is derived by performing a cryptographic transformation (see cryptography) on the data unit. The derivation of the checkvalue may be performed in one or more steps and is a result of a mathematical function of the key and a data unit. It is usually used to check the integrity of a data unit.Examples:

    * SHA-1 * SHA-2 (Secure Hash Algorithm)
