What AI says about Kerberos

Kerberos is a network authentication protocol designed to provide strong authentication for client/server applications using secret-key cryptography. MIT provides a free implementation of Kerberos (krb5), with source code, binaries, releases, and documentation, and Kerberos is also offered by many commercial products. It enables mutual authentication between clients and servers and can encrypt communications to ensure privacy and data integrity over insecure networks.
