ISO/TC 154/WG 6 - Trusted eCommunications

This document specifies the elements, among those defined in XAdES digital signatures, that enable verification of a digital signature over a long period of time. It does not give new technical specifications about the digital signature itself, nor new restrictions of usage of the technical specifications about the digital signatures which already exist. NOTE XAdES digital signatures is the widely-used extended specification of “XML-Signature Syntax and Processing”.

As a connected standard of ISO 19626-1, this document defines the communication interactions between TCP system components and specifies their detailed interfaces — the processes and the APIs of the TCP system components. It provides the common communication interface for deployment and implementation of the system components, and their functions in a specific technology-neutral way to those who consider applying and establishing a TCP system.

This document defines the requirements about trusted communication in legal, administrative and technical considerations. This document shows a TCP system architecture to guarantee trusted communication and promote trusted services by providing trusted communication evidence as the proof. This document focuses on TCP at the view of 7th application layer of OSI (Open Systems Interconnection) Reference Model. The audiences are the policy makers for IT innovation such as dematerialization, legal experts regarding electronic activities, IT planners for single windows and secure transactions, IT service providers related to distributed networking and ledger, trusted system auditors, trusted communication concerned parties and so on.

This document provides a set of requirements, functionality and criteria for ensuring reliability and safety of mobile e-business. The specification of this document covers overall use cases for mobile e-business including simple inquiry of electronic documents, exchange of electronic documents for general transaction and even exchange of contract and payment documents. This can be applied to the most wireless protocols such as 3G, 4G and Wi-Fi, etc. This could be also used in the general mobile e-business area such as logistics, electronic trades, financing, manufacturing and service, and can be referenced by system developers of electronic transaction using mobile devices, mobile network service providers and users.

This document 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. It 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 PoE attributes pointing to (external) PoE objects used in long term signature validation or preservation.

ISO 14533-3:2017 specifies the elements, among those defined in PDF Advanced Electronic Signatures (PAdES), that enable verification of a digital signature over a long period of time. It does not give new technical specifications about the digital signature itself, nor new restrictions of usage of the technical specifications about the digital signatures which already exist.
