What is ISO 14533-4 - PoE Attributes in long term signature about?
ISO 14533-4 specifies the elements defined in the international standards of ISO/ITU-T, ETSI and IETF RFC that enable at least a proof of existence of data objects and digital signatures and the preservation of the validity status of digital signatures over a long period of time used in validation.
ISO 14533-4 provides the definitions of the proof of existence (PoE) attributes and clarification of the usage of (external) PoE objects, with digital signatures and trusted time values, which have already existed and can be used by the proof of existence attributes pointing to proof of existence objects used in long term signature validation or preservation.
ISO 14533-4 specifies the proof of existence attribute as an object which provides a reference between optional data objects and the trusted evidence of at least one property of the data object or a set of data objects, especially the integrity, status, type of data object or type of interpretation at a specific time interval or at the date and time.
