Overview Kerberos是一个第三方认证机制,用户和服务(known as principals)通过kerberos server (known as the Key Distribution Center, or KDC)认证彼此.KDC有三部分: A database of principals and their Kerberos passwords An Authentication Server (AS) which performs the initial authent

Kerberos是一种安全认证协议,意在提供 more secure authentication simplified management of password convenience of single sign on Kerberos的基本结构 Kerberos Client: 申请服务的一方 Kerberized Service: 提供服务的一方 Kerberos KDC: 提供密码管理的认证的一方.Client和service provider都会将自己的私密保存在KDC中.
Kerberos客户端常用命令包括 kinit, klist, kdestroy, and kpasswd,用户使用这些命令管理自己的 ticket. 此外,每台运行Kerberos的机器应该都配置/etc/krb5.conf,At a minimum, it should define a default_realm setting in [libdefaults]. If you are not using DNS SRV records, it must also contain a [r
Kerberos是一种计算机网络授权协议,用来在非安全网络中,对个人通信以安全的手段进行身份认证. 采用客户端/服务器结构,并且能够进行相互认证,即客户端和服务器端均可对对方进行身份认证. 关键要素 KDC:Key Distribution Center – Each user and service shares a secret key with the KDC – The KDC generates and distributes session keys – Communicating
1.1 What is Kerberos 1.1.1 简单介绍 Kerberos是一个用于鉴定身份(authentication)的协议, 它采取对称密钥加密(symmetric-key cryptography),这意味着密钥不会在网络上传输.在Kerberos中,未加密的密码(unencrypted password)不会在网络上传输,因此攻击者无法通过嗅探网络来偷取用户的密码. Kerberos利用对称加密和受信任的第三方(即KDC, key distribution center)来鉴别
