![]() Microsoft has their very own version of Kerberos, krw, for their proprietary NT kernel. The version of Kerberos that MIT develops (krb) is used in BSD/Unix and GNU/Linux kernel operating systems. Therefore, MIT’s Kerberos code may be freely used and distributed, but not modified. MIT’s Kerberos software is FOSS (opensource), but under a BSD-like license rather than a share-alike “copyleft” sort of license, such as the GNU General Public License. Legacy versions of Kerberos used DES, which is incredibly insecure these days. Kerberos 5 (krb5-x) uses AES with 128-bit blocks and key sizes of 128 or 256 bits. The authentication server forwards client usernames to a key distribution center (KDC). Between the client and server, a Kerberos authentication server acts as the trusted third party. Kerberos uses symmetric cryptographic algorithms, and may use public-key cryptography. Both the client and the server authenticate each other with packets sent through the Kerberos protocol, usually designated to UDP port 88. It works by using tickets to authenticate authorized clients to authorized servers, and vice versa- thus mitigating man-in-the-middle and reply attacks. It allows nodes to communicate more securely through insecure networks, such as most internet protocols, like HTTP and FTP. ![]() The latest stable release of Kerberos is krb5-1.13, as of October 15 th, 2014. It’s a project of the Massachusetts Institute of Technology (MIT), and its first stable version was released all the way back in 1987. Kerberos is a protocol for network authentication.
