Abstract

A method and apparatus for reprogramming a digital electronic device or Appliance is provided. A preferred embodiment locates a reprogrammable Controller chip in the communications flow between a reprogrammable digital device and an application server. The application server transmits commands and programming data to the Controller chip in data packets via the Internet. The Controller sniffs each data packet to determine the type of data contained therein. The Controller will immediately forward certain types of data packet onto the digital device. Alternatively, the Controller may store data packets that relate to the reprogramming of either the digital device or the Controller itself, for collation and later transference during a reprogramming of the digital device or the Controller. Data packets may contain upgrade data, status queries, monitoring instructions, logic settings, and other information relating to the operation and status of the server, device or Controller. The application server of the preferred embodiment transmits Controller and device specific instruction commands via the Internet that are related to the native language of the Controller and/or the digital device. The device may be programmed to periodically check in with the applications server for purposes such as security, reporting, maintenance and/or refreshing the operational methodology of the system. The periodic check-ins maybe real time based, time-period based and/or event driven. The Controller may optionally be accelerated by a high performance processor. The Controller may use PKI encryption techniques, store public keys and private keys, and generate public/private key pairs.

10. The method of claim 1, wherein the processing instructions direct the controller to transfer the data to the target and bypass the memory.

11. The method of claim 1, further comprising the target peforming a self-test after receiving the data from the controller.

12. The method of claim 11, further comprising a selective delivery of data from the memory after the target fails a self test.

13. The method of claim 11, further comprising a notification by the target to the controller of a failure of a self test by the target.

14. The method of claim 1, further comprising;

providing a server and coupling the server to the computer network; and

requiring the target to communicate with server periodically in order for the controller to continue functioning.

15. The method of claim 1, further comprising the provision and use of a hardware accelerator with the controller, whereby the controller speed of operation is increased.

16. The method of claim 1, further comprising the generation of communication transaction identifier records, wherein the message transmitted by the controller over the computer network includes information identifying the message addressee and the message originator.

17. The method of claim 5, further comprising the provision and use of more than two sectors of memory.

19. The method of claim 1, further comprising the use of a public and private encryption key pair, wherein the data is encrypted with the private key prior to transmission via the computer network and a message controller uses the public key to decrypt the data.

20. The method of claim 1, further comprising the generation and use by the controller of a controller public and private encryption key pair, wherein the controller transmits the controller public key to an addressee, and the controller encrypts a portion of a message with the controller private key, and the controller transmits the message after encryption to the addressee.
