Benefits of technology

[0007]A method, programmed medium and system are provided for enabling a user to choose a user-preferred encryption type from among a plurality of encryption types listed in a user's Kerberos configuration file. In one example, during the ticket granting process in a Kerberos system, a user is requested to select a preferred encryption type to be used in the Kerberos communication from among encryption types contained in the user's Kerberos configuration file. The user

Embodiment Construction

[0012]The various methods discussed herein may be implemented within a computer system which includes processing means, memory, storage means, input means and display means. Since the individual components of a computer system which may be used to implement the functions used in practicing the present invention are generally known in the art and composed of electronic components and circuits which are also generally known to those skilled in the art, circuit details beyond those shown are not specified to any greater extent than that considered necessary as illustrated, for the understanding and appreciation of the underlying concepts of the present invention and in order not to obfuscate or distract from the teachings of the present invention. Although the invention is illustrated in the context of a networked computer system, it is understood that disclosed methodology may also be applied in many other available and future devices and systems such as cell phone networks and personal

Abstract

A method, programmed medium and system are provided for enabling a user to choose a user-preferred encryption type from among a plurality of encryption types listed in a user's Kerberos configuration file. During the ticket granting process in a Kerberos system, a user is requested to select a preferred encryption type to be used in the Kerberos communication from among encryption types contained in the user's Kerberos configuration file. The user-selected encryption type is then implemented for use in encrypting a session ticket (as well as generating the session key of user requested encryption type) for use by the user machine in communicating securely with an Kerberized application server when being communicated by that particular user. Thus, the system allows different users to simultaneously communicate with the same Kerberized application server using a supported encryption type of the user's own choice.
