Kerberos, SESAME, directory
services, and thin clients are examples of single sign-on technologies.Users
enter only one set of credentials,which allows themto access all the network resources
they require. Kerberos is a ticket-based authentication protocol that
uses symmetric cryptography.SESAME is similar toKerberos, was developed to
overcome some of Kerberos shortcomings, and uses public key cryptography.
Kerberos and SESAME are both vulnerable to dictionary attacks.
