Ans. CFH C. eFuse: eFuses can be used to create a tamper-resistant counter that tracks whether unapproved firmware has been loaded. They can be programmed to change state permanently when certain conditions are met, making them useful for integrity checks. F. Secure boot: Secure boot ensures that only authorized firmware is loaded on the device at startup. It verifies the digital signatures of the firmware and helps prevent the loading of unapproved or malicious firmware. H. Secure enclave: A secure enclave provides a hardware-based trusted execution environment where sensitive operations, like storing biometric data, can be performed securely. It helps protect sensitive information from unauthorized access.
