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.
