Authentication system and method for providing access for a subsystem to a password-protected main system
First Claim
1. A method for providing access for at least one subsystem to at least one password-protected main system using an authentication system, the method comprising:
- receiving, by the authentication system, a prescribed key stored in the subsystem;
comparing the received key with a reference key stored in the authentication system;
reading a reversibly coded password for the main system, stored in the authentication system, and decoding the password if the received key matches the reference key; and
outputting the password to the main system, upon being decoded, to provide access for the subsystem.

Abstract
An authentication system is proposed, for providing access for at least one subsystem to at least one password-protected main system. The authentication system includes a memory device for storing at least one reference key for the at least one subsystem and at least one reversibly coded password for the main system. It further includes a reception device for receiving a prescribed key stored in the subsystem. In addition, a comparison device is included for comparing the received key with the at least one reference key stored in the memory device. Further, a decoding device is used for reading and decoding the at least one reversibly coded password for the at least one main system which is stored in the memory device, if the requested key matches the reference key. Finally, an output device is included for outputting the decoded password to the main system in order to provide access for the subsystem. In addition, a method is proposed for providing access for at least one subsystem to at least one password-protected main system using an authentication system.

7. An authentication system for providing access for at least one subsystem to at least one password- protected main system, the authentication system comprising:
-
a memory device, adapted to store at least one reference key for the at least one subsystem and at least one reversibly coded password for the main system;
a reception device, adapted to receive a prescribed key stored in the subsystem;
a comparison device, adapted to compare the received key with the at least one reference key stored in the memory device;
a decoding device, adapted to read and decode the at least one reversibly coded password, for the at least one main system which is stored in the memory device, if the received key matches the reference key; and
an output device, adapted to output the password to the main system upon being decoded, in order to provide access for the subsystem. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 21)
