Abstract

Methods and systems are provided for updating a base file used by certified software that is executing on a processor within a first computing device without breaking a certification of the software. The method comprises receiving a software object at a communications interface of the first computing device, the software object containing instructions that when executed by the processor interfaces with the certified software and integrates a delta file with the base file to create an updated file within the first computing device. The method further comprises installing the software object in a random access memory (RAM) and initializing the software object in the processor from the RAM. After installing the software object, receiving the delta file and providing the delta file for combination with the base file by the software object and after the combination is complete, erasing the software object from the RAM.

Claims

1. ) A method for updating a base file used by certified software executing on a processor within a first computing device without breaking a certification of the software, comprising:

receiving a software object at a communications interface of the first computing device, the software object containing instructions that when executed by the processor interfaces with the certified software and integrates a delta file with the base file to create an updated file within the first computing device;

installing the software object in a random access memory (RAM) and initializing the software object in the processor from the RAM;

after installing the software object, receiving the delta file and providing the delta file for combination with the base file by the software object; and

after the combination is complete, erasing the software object from the RAM.

2. ) The method of claim 1, where the software object is an applet.

3. ) The method of claim 1, wherein the delta file accompanies the software object.

4. ) The method of claim 1, wherein the certified software executes from read only memory.

5. ) The method of claim 1, wherein the RAM is only capable of recording during a download mode of the first computing device.

6. ) The method of claim 5, wherein the RAM is automatically erased during a transition from the first mode to a second mode.

7. ) The method of claim 1, wherein the software object is accompanied by a cyclical redundancy check (CRC) designed to verify the combined base file and the delta file.

8. ) The method of claim 7, wherein the certified software includes a CRC verification algorithm.

9. ) A system for updating a base file used by certified software that is executing on a processor within a second computing device without breaching a certification of the software, comprising:

a first computing device containing a software object recorded therein, the first computing device configured to supply a delta file that updates the base file; and

a second computing device, the second computing device comprising;

a processor;

a random access memory (RAM); and

a communication interface in electronic communication with the first computing device, the processor and the RAM, the communication interface being configured to;

receive the software object and the delta file from the first computing device, the software object containing instructions that when executed by the processor interfaces with the certified software and integrates a delta file with the base file to create an updated data file within the second computing device;

install the software object in the random access memory (RAM);

initialize the software object in the processor from the RAM;

after installing the software object, provide the delta file for combination with the base file by the software object; and

after the combination is complete, erasing the software object from the RAM.

10. ) The system of claim 9, where the software object is an applet.

11. ) The system of claim 9, wherein the delta file and the software object. Are received together.

12. ) The system of claim 9, wherein the software object is received prior to receiving the delta file.

13. ) The system of claim 9, wherein the certified software executes from read only memory

14. ) The system of claim 9, wherein the RAM is only capable of recording during a download mode of the second computing device.

15. ) The system of claim 14, wherein the RAM is automatically erased during a transition from the first mode to a second mode.

16. ) The method of claim 9 wherein the software object is also accompanied by a cyclical redundancy check (CRC) designed to verify the combined base file and the delta file in conjunction with a CRC algorithm resident within the processor.
