Kerberos在既有系统身份认证中的应用
Title:KerberosinApplicationforExistingSystemIdentityAuthentication
1.Introduction:
Intoday'sera,withtheincreasingrelianceondigitalsystemsandnetworks,ensuringsecureauthenticationandaccesscontroltothesesystemshasbecomeimperative.Protectingsystemidentityandusercredentialsfromunauthorizedaccessiscrucialtopreventdatabreachesandcyber-attacks.Kerberosisawidelyadoptedauthenticationprotocolthatprovidessecure,trusted,andcentralizedauthenticationforexistingsystems.ThispaperexaminestheapplicationofKerberosinexistingsystemidentityauthenticationandhighlightsitsbenefitsandchallenges.
