Maskinautentisering, often shortened to machine authentication, refers to the process by which a machine, such as a server, device, or application, verifies its identity to another machine or system. This is distinct from user authentication, which verifies the identity of a human user. The primary goal of machine authentication is to ensure that only authorized machines can access sensitive resources, communicate with specific services, or participate in a network.

Common methods for machine authentication include the use of digital certificates, pre-shared keys, or tokens. Digital certificates, issued by a trusted Certificate Authority (CA), contain cryptographic information that allows one machine to verify the authenticity of another. Pre-shared keys involve a secret key or password that is shared between the authenticating parties beforehand. Tokens, such as OAuth tokens or API keys, are credentials that grant specific access rights to a machine for a limited time or for particular operations.

Machine authentication is crucial for securing various technological interactions. It is widely employed in scenarios like secure API communication, where one service needs to authenticate itself to another before exchanging data. It is also fundamental in securing the Internet of Things (IoT), ensuring that connected devices are legitimate and not malicious. Furthermore, it plays a vital role in network access control, preventing unauthorized devices from joining a network. Implementing robust machine authentication mechanisms is a key component of modern cybersecurity strategies.
