Authentication of Principals

Kerberos for z/OS verifies requests as a trusted third party authentication service. Using conventional shared key cryptography, Kerberos confirms the identities of principals (users):

• Without relying on authentication by the host operating system
• Without basing trust on host addresses
• Without necessitating physical security of all hosts on the network
• Under the premise that packets traveling along the network can be read, changed, and inserted at will
