and administration - Trusted communication platform for electronic documents
1 Scope
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.

3.1 blacklist
list of e-identities (13) of the originators who are proved having ‘malicious intent’
Note ito entry: If a message is confirmed as spam (15), an e-identity who sent the spam is classified as a sender having ‘malicious intent’.
Note 2 to entry: An addressee receiving a message from the originator in the blacklist can reject receiving the message.
3.2 characteristic information
unique identifying information to identify the entity in the offline (real) world such as a resident registration number, social security number, or identification number of an loT device
4.1 Overview
ISO 19626-1 presents 2 types of 'TCP main' and 'TCP client' in system architecture. As a connected standard, this document enhances its relational architecture at the view of the interface.
As shown in Figure 1, once a transmitting entity (i.e. a sender) makes a delivery request to a receiving entity (i.e. a receiver), each of the components can be linked to one another through linkage interfaces,and the communication server is enabled to form an entrusted chain with a relying party. The pair-linked communication servers implement communication that can be entrusted, and through their interactions, generate TCE and can possess evidence in the TCE repository.
4.2 TCP relational architecture
Even if some communities intend to establish a TCP, they could not implement it in case their business and technical environments are different.
The particular authentication level, applied technology and communication protocol, etc. in each linkage need to be arranged properly by designing after classifying TCP main' and TCP client' even under various existing legacy system environments (refer to the ISO 19626-1:2020, 5.2).
