A mobile device hardware manufacturer receives the following requirements from a company that wants to produce and sell a new mobile platform:
*The platform should store biometric data.
*The platform should prevent unapproved firmware from being loaded.
* A tamper-resistant, hardware-based counter should track if unapproved firmware was loaded.
Which of the following should the hardware manufacturer implement? (Select three).
Correct Answer: C,F,H
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.
