Abstract

A wireless system may include a separately accessible protocol stack and security services module. The security services module may handle cryptographic algorithms and other security services. Since the modules are separately accessible, the protocol stack may be developed, tested and updated independently of the security services module and vice versa.

Claims

1. A method comprising:

providing a protocol stack for wireless communications;

providing a security services module; and

enabling said module to be accessed separately from said stack.

2. The method of claim 1 including enabling the protocol stack to obtain security services from the security services module.

3. The method of claim 1 wherein providing security services includes providing encryption, verification, or authentication services.

4. The method of claim 1 wherein providing a security services module includes providing a security services module including a cryptographic library.

5. The method of claim 4 wherein providing a cryptographic library includes providing one of the Diffie Hellman, f8, and advanced encryption standard algorithms.

6. The method of claim 1 including providing security services for the protocol stack and application execution environment.

7. A wireless system comprising:

a processor; and

a storage coupled to said processor, said storage storing a separately accessible protocol stack and a security services software module.

8. The system of claim 7 wherein said processor enables the protocol stack to obtain security services from the security services module.

9. The system of claim 7 wherein said system is a wireless telephone.

10. The system of claim 7 wherein said security services software module provides encryption, verification, or authentication services.

11. The system of claim 7 wherein said software module provides a cryptographic algorithm library.

12. The system of claim 11 wherein said cryptographic algorithm is one of the Diffie Hellman, f8, or advanced encryption standard algorithms.

13. The system of claim 7 wherein said module provides security services for the protocol stack and an application execution environment.

14. A cellular telephone comprising:

a processor; and

a first storage coupled to said processor, first said storage storing a protocol stack; and

a second storage coupled to said processor, said second storage storing a security services software module, said protocol stack and module being separately accessible.

15. The telephone of claim 14 wherein said processor enables the protocol stack to obtain security services from the security services module.

16. The telephone of claim 14 wherein said security services software module provides encryption, verification, or authentication services.

17. The telephone of claim 14 wherein said software module provides a cryptographic algorithm.

18. The telephone of claim 17 wherein said cryptographic algorithm is one of the Diffie Hellman, f8, or advanced encryption standard algorithms.

19. The telephone of claim 14 wherein said module provides security services for the protocol stack and an application execution environment.

20. The telephone of claim 14 including a memory device, said first and second storage being part of said memory device.
