Abstract
Techniques are disclosed for providing secure critical security parameter (CSP) generation in an integrated circuit (IC). Embodiments generally include determining that an ability to read the CSP externally (e.g., through a debug interface) has been disabled before the CSP is generated. Depending on the functionality of the device, embodiments can include other steps, such as determining whether software for executing a method for providing a secure CSP is being run for a first time. Among other things, the techniques provided herein for providing secure CSP generation can increase the security of the CSP and reduce manufacturing costs of the IC.
