Digital selective calling (DSC) is a standard for transmitting predefined digital messages via the medium-frequency (MF), high-frequency (HF) and very-high-frequency (VHF) maritime radio systems. It is a core part of the Global Maritime Distress Safety System (GMDSS). [1]
Public key infrastructure. A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network ...
Each DSC-equipped ship, shore station and group is assigned a unique 9-digit Maritime Mobile Service Identity. DSC distress alerts, which consist of a preformatted distress message, are used to initiate emergency communications with ships and rescue coordination centers.
A digital signature is an authentication mechanism that enables the creator of the message to attach a code that acts as a signature. The Digital Signature Algorithm (DSA), developed by the National Institute of Standards and Technology, is one of many examples of a signing algorithm.
Maritime identification digits. Maritime identification digits are used by radio communication facilities to identify their home country or base area in digital selective calling (DSC), Automatic Transmitter Identification System (ATIS), and Automatic identification system (AIS) messages as part of their Maritime Mobile Service Identities.
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. [1] In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
Simple Certificate Enrollment Protocol. Simple Certificate Enrollment Protocol (SCEP) is described by the informational RFC 8894. Older versions of this protocol became a de facto industrial standard for pragmatic provisioning of digital certificates mostly for network equipment. The protocol has been designed to make the request and issuing of ...
The Automatic Certificate Management Environment (ACME) protocol is a communications protocol for automating interactions between certificate authorities and their users' servers, allowing the automated deployment of public key infrastructure at very low cost. [1][2] It was designed by the Internet Security Research Group (ISRG) for their Let's ...
