To meet the mobile platform security requirements, the manufacturer should implement the following technologies:
eFuse: This hardware feature helps track and prevent unauthorized firmware by physically "blowing" fuses to record events, such as firmware tampering, making it impossible to revert to older, unapproved firmware.
Secure boot: This ensures that only trusted and authorized firmware can be loaded during the boot process, preventing malicious or unauthorized software from running.
Secure enclave: A secure enclave is used to store sensitive information like biometric data in a hardware-isolated environment, protecting it from tampering or unauthorized access.
These three solutions provide the tamper resistance, secure firmware validation, and protection of sensitive data required for the platform. CASP+ emphasizes the use of hardware-based security features for protecting sensitive information and enforcing secure boot processes in embedded and mobile systems.
