METHOD AND SYSTEM FOR ALLOWING CUSTOMER OR THIRD PARTY TESTING OF SECURE PROGRAMMABLE CODE
Abstract:
Methods and systems for allowing customer or third party testing of secure programmable code are disclosed and may include verifying code loaded in a set-top box utilizing a test hash or a production hash prior to execution of the code, where the test hash and production hash may be stored in a memory, such as an OTP, within the set-top box, and may allow migration from corresponding test code to production code, which may be verified utilizing the test hash and production hash, respectively. The test and production hashes may be customer specific. The migration from test code to production code may be authenticated using at least a set-top box specific password. The test hash may be stored in a first portion of a one-time programmable memory and the production hash in a remaining portion, with the first portion being less than or equal to the remaining portion.
