Abstract

A method is provided for transmitting encrypted information for registering an application program. An application program installed on a first program is control device. First application information items having at least one part-information item blocked from user access are transmitted to a second program control device. The second program control device uses coding to calculate an application value from the first application information items. The application value is transmitted to the first program control device. The first program control device uses decoding to ascertain second application information items from the application value. The first application information items and the second application information items are checked for a match when the application program starts to be executed. Prescribable functions of the application program are enabled on the basis of discrepancies resulting from the check.

Claims

1. A method for transmitting encrypted information for registering an application program installed on a first program control device, comprising the steps of:

transmitting first application information items to a second program control device, said first application information items having at least one part-information item blocked from user access,

the second program control device calculating an application value from the first application information items using coding,

transmitting the application value to the first program control device;

the first program control device ascertaining second application information items from the application value (Y) using decoding,

checking the first application information items and the second application information items for a match when the application program starts to be executed, and

enabling prescribable functions of the application program on the basis of the discrepancies resulting from the checking step.

2. The method as claimed in claim 1, further comprising the step of storing the first application information items in encrypted form distributed over a memory device associated with the first program control device.

3. The method as claimed in claim 2, further comprising the step of activating or deactivating service features available in a communication system through enabling functions of the application program.

4. The method as claimed in one of claim 3, wherein at least one of the steps of transmitting the first application information items and transmitting the application value is carried out via a network which provides connectionless services.

5. The method as claimed in claim 4, wherein at least one of the first application information items and the application value is transmitted by e-mail.

6. The method as claimed in one of claim 5, wherein at least one of the first application information items and the application value is transmitted by program control element.

7. The method as claimed in one of claims 6, wherein at least one of the first application information items comprise at least one of part-information items relating to program control devices, part-information items relating to application programs and part-information items items relating to users.

8. The method as claimed in one of claim 4, wherein at least one of the first application information items and the application value is transmitted by program control element.

9. The method as claimed in one of claims 8, wherein at least one of the first application information items comprise at least one of part-information items relating to program control devices, part-information items relating to application programs and part-information items items relating to users.

10. The method as claimed in one of claim 1, wherein at least one of the steps of transmitting the first application information items and transmitting the application value is carried out via a network which provides connectionless services.

11. The method as claimed in claim 10, wherein at least one of the first application information items and the application value is transmitted by e-mail.

12. The method as claimed in one of claim 11, wherein at least one of the first application information items and the application value is transmitted by program control element.

13. The method as claimed in one of claims 12, wherein at least one of the first application information items comprise at least one of part-information items relating to program control devices, part-information items relating to application programs and part-information items items relating to users.

14. The method as claimed in one of claim 10, wherein at least one of the first application information items and the application value is transmitted by program control element.

15. The method as claimed in claim 1, further comprising the step of activating or deactivating service features available in a communication system through enabling functions of the application program.

16. The method as claimed in one of claims 1, wherein at least one of the first application information items comprise at least one of part-information items relating to program control devices, part-information items relating to application programs and part-information items items relating to users.

17. The method as claimed in one of claims 2, wherein at least one of the first application information items comprise at least one of part-information items relating to program control devices, part-information items relating to application programs and part-information items items relating to users.

18. The method as claimed in one of claims 3, wherein at least one of the first application information items comprise at least one of part-information items relating to program control devices, part-information items relating to application programs and part-information items items relating to users.

19. The method as claimed in one of claims 4, wherein at least one of the first application information items comprise at least one of part-information items relating to program control devices, part-information items relating to application programs and part-information items items relating to users.

20. The method as claimed in one of claim 2, wherein at least one of the steps of transmitting the first application information items and transmitting the application value is carried out via a network which provides connectionless services.
