NTP authentication is a method used to ensure that authenticated peers are actually communicating with the NTP server they expect. It is a security measure designed to protect against man–in–the–middle attacks, where an attacker could intercept and manipulate the interaction between two parties. NTP authentication works by using public key encryption and an authentication key generated by the NTP server.

The 7 layer network model, also known as the OSI (Open Systems Interconnection) model, is a reference model used to help define the functions of networking and communications components. The layer model is composed of seven distinct layers, which are (from lowest to highest): Physical Layer, Data Link Layer, Network Layer, Transport Layer, Session Layer, Presentation Layer, and Application Layer. Each layer plays a specific role in the networking process and provides services to the higher–level layers.
