IEC 63173-2:20 22船岸安全通信（SECOM）的范围包括用于数据交换（信息服务）的接口（API）、实现安全通信的信息安全措施以及用于服务可发现性的接口。SECOM提供技术互操作性，其中相同的服务接口用于交换信息，而不管其操作用途如何，直至安全地在线交换信息。虽然SECOM是为基于IHO S-100的产品设计的，但在技术上与有效载荷无关，也适用于其他类型的数据。 SECOM信息服务之间用于数据交换的通信依赖于基于IP的web服务。本文档中没有定义SECOM信息服务和最终用户应用程序之间的“最后一英里”链接，因此供应商API和船/岸系统之间的通信技术可以是非基于IP以及基于IP。资料性附件D描述了一种这样的实现。这允许在服务和岸/船™的系统/应用之间提供不同的解决方案。 SECOM没有为SECOM信息服务之间的数据传输定义物理层或链路层，但要求传输支持IP通信。SECOM适用于公共（政府）和私人（商业）服务。SECOM适用于船岸和岸船通信，可用于船船通信。

IEC 63173-2:2022 the scope of secure communication between ship and shore (SECOM) includes interfaces (APIs) for data exchange (information services), information security measures to enable secure communication and interfaces for service discoverability. SECOM provides technical interoperability, where the same service interface is used for exchanging the information regardless of its operational use, up to the level of exchanging information securely online. Although designed for IHO S-100 based products, SECOM is technically payload agnostic and applicable also for other types of data.
Communication between SECOM information services for data exchange relies on IP based web services. The "last mile" links between a SECOM information service and the end-user application is not defined in this document, thus the communication technology between the vendor API and a ship/shore system can be non-IP based as well as IP based. The informative Annex D describes one such implementation of this. This allows different solutions between the service and shore/ship’s system/applications.
SECOM does not define physical layer or link layer for transport of data between SECOM information services, but requires that the transport supports IP communication. SECOM is applicable for both public (governmental) and private (business) services. SECOM is applicable for ship-shore and shore-ship communication, and can be used for ship-ship communication.
