Abstract
Techniques for improving security of an electronics device are disclosed. In one aspect of the present disclosure, security of a device may be improved by generating a working key based on a hardware secret key and at least one security parameter of the device, e.g., with a key derivation function. The security parameter(s) may be related to software to be authenticated on the device and/or other aspects of security for the wireless device. The security parameter(s) may indicate whether the software is authorized and/or at least one operating function authorized for the software. At least one security function may be performed for the device based on the working key. For example, the working key may be used to encrypt, sign, decrypt, or verify data for the device. The working key may be used directly or indirectly by the software for the at least one security function.
