Abstract

Claims (29)

1. A system for generating cryptographic material, the system comprising:

a developer module, wherein the developer module has a user interface or is coupled directly or indirectly to the user interface, wherein the user interface is configured to accept an input of specifications, in abstract form, for generating a program in a syntax of a cryptomaterial generator or to translate the input specifications into a series of commands of a higher-level programming language executable by the cryptomaterial generator;

a transformation module configured to automatically transform the input specifications into the program in the syntax of the cryptomaterial generator or into the series of commands of the higher-level programming language; and

a cryptomaterial server comprising

the cryptomaterial generator, which is configured to generate cryptographic material based on the inputted specifications by executing the program or by executing the series of commands in the higher-level programming language; and

a cryptomaterial distributor,

wherein the cryptomaterial server and the developer module has a corresponding sending part of the specification interface, wherein the receiving and sending parts of the specification interface are couplable directly or indirectly for the secure transmission of data.

2. The system of claim 1 , wherein the transformation module is part of the cryptomaterial generator.

3. The system of claim 1 , wherein the cryptomaterial generator has a hardware security module configured to generate the cryptographic material.

4. The system of claim 3 , wherein the syntax of the cryptomaterial generator is predetermined by a syntax of the hardware security module.

5. The system of claim 1 , wherein the cryptomaterial server further comprises a cryptomaterial database storing the cryptographic material generated by the cryptomaterial generator.

6. The system of claim 5 , wherein the cryptomaterial distributor is connected to the cryptomaterial generator directly or indirectly via the cryptomaterial database.

7. The system of claim 6 , wherein the cryptomaterial database is directly connected to a hardware security module of the cryptomaterial generator and in parallel to the transformation module in the cryptomaterial generator.

8. The system of claim 1 , wherein the cryptomaterial generator further comprises a specification database.

9. The system of claim 1 , wherein the transformation module comprises an interpreter configured to generate the series of commands of the higher-level programming language.

10. The system of claim 1 , wherein the transformation module comprises a translator configured to generate the program in the syntax of the cryptomaterial generator.

11. The system of claim 1 , wherein the user interface comprises a text-oriented or graphic-oriented syntax-controlled editor configured to input the specifications in the abstract form.

12. The system of claim 1 , wherein the user interface comprises checking modules configured to check the syntax of the cryptomaterial generator or to check a type of the input of the specifications.

13. The system of claim 1 , wherein the user interface is configured to process the input of the specifications in a declarative, non-operational form.

14. The system of claim 1 , wherein the cryptomaterial server further comprises a distributing interface, wherein the cryptomaterial distributor is connected directly or indirectly to at least one receiver or user of the cryptographic material via the distributing interface.

15. A method, comprising:

predetermining, by a developer module, specifications for a specific application of a vehicle-specific information technology system, wherein the specifications are predetermined via a user interface that accepts an input of the specifications in abstract form;

receiving, by the cryptomaterial server from the developer module, the specifications;

automatically transforming, by a transformation module, the specifications into program in a syntax used by a cryptomaterial generator or into a series of commands of a higher-level programming language executable by the cryptomaterial generator;

receiving, by a cryptomaterial server from the transformation module, the program based on the specifications; and

generating the cryptomaterial, wherein the cryptomaterial is generated, by the cryptomaterial generator executing the program based on the specifications or by executing the series of commands in the higher-level programming language; and

distributing the generated cryptographic material to a receiver or user of the specific application.

16. The method of claim 15 , wherein cryptomaterial generator includes a hardware security module that generates the cryptomaterial, wherein the syntax used by the cryptomaterial generator is predetermined by a syntax used by the hardware security module.

17. The method of claim 15 , wherein the user interface comprises a text-oriented or graphic-oriented syntax-controlled editor via which the specifications are input in the abstract form.
