Abstract

The software stored in the non-secure storage device is authenticated when the software is first loaded for execution by the device. Authenticating the software may involve a cryptographic operation of the software and a digital signature of the software. If authentication of the software is successful, an authentication tag for the software can be generated, the authentication tag being based on the software and at least device specific secret data. The authentication tag may be stored within the device. Then whenever the software is loaded for execution, the software can be verified (not certified) by using the verification tag to confirm that the software being loaded is the same software that was used to generate the verification tag , while avoiding authentication of the software.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit from non-provisional application Ser. No. 14 / 687,783, filed April 15, 2015, in the United States Patent and Trademark Office, which is hereby incorporated by reference in its entirety. technical field [0003] Various features disclosed herein relate generally to authentication of software to reduce hacking of software in devices lacking secure storage, and more particularly to a method of performing software authentication when the software is first executed and thereafter. A more efficient approach to software verification. Background technique [0004] such as a mobile phone, nomadic device, pager, wireless modem, personal digital assistant, tablet computer, personal information manager (PIM), personal media player, palmtop computer, laptop computer, or any other device with a processor Devices are becoming more popular and ubiquitous.
