Authentication server

An '''authentication server''' provides a network service that applications use to authenticate the credentials,<ref>{{Cite journal|last1=Hong|first1=S.-M.|last2=Lee|first2=S.|last3=Park|first3=Y.|last4=Cho|first4=Y.|last5=Yoon|first5=H.|date=2000-11-01|title=On the construction of a powerful distributed authentication server without additional key management|url=https://linkinghub.elsevier.com/retrieve/pii/S0140366400002504|journal=Computer Communications|language=en|volume=23|issue=17|pages=1638–1644|doi=10.1016/S0140-3664(00)00250-4|url-access=subscription}}</ref> usually account names and passwords, of their users. When a client submits a valid set of credentials, it receives a cryptographic ticket that it can subsequently use to access various services.<ref>{{Cite web |title=How the Kerberos Service Works - Managing Kerberos in Oracle® Solaris 11.4 |url=https://docs.oracle.com/cd/E37838_01/html/E61026/kerbov-works.html |access-date=2025-08-17 |website=docs.oracle.com}}</ref>

Authentication is used as the basis for authorization, which is the determination whether a privilege may be granted to a particular user or process, privacy, which keeps information from becoming known to non-participants, and non-repudiation, which is the inability to deny having done something that was authorized to be done based on the authentication.

Major authentication algorithms include passwords, Kerberos, and public key encryption.
