Kerberos

Kerberos refers to a service whose purpose is to enable users and systems to authenticate and confirm their identity.

One of the common techniques related to Kerberos is the use of passwords. The user enters his password on the log-in form provided by the server. The server then checks if the password is valid. If it is, the server will allow the user to access its information.

Kerberos involves innovations which generally state that passwords and similar verification strategies should be viewed as only special cases of a shared secret. Owing to this, Kerberos has developed a new technique in confirming the identity of users. This technique is done through the use of an encryption key.

How Does Kerberos Implement Encryption Keys?

The encryption key is then sent to the server, which will check the user’s identity by decrypting the key. If the user entered the right secret key along with his timestamp, the system will properly decrypt the encryption key. Consequently, the system will accept the user’s login attempt. Otherwise, if the user entered the wrong secret key, the system will not decrypt the information properly and it will deny access to the user.

Kerberos includes additional subsystems to improve its functions. These components address the issues of unexpected problems that may happen during the encryption process and speed up the validation procedures.
