Secure Boot
A hardware-level security mechanism that verifies firmware digital signatures level by level through a chain of trust to prevent unauthorized firmware from loading. It is a core technology for preventing firmware tampering on modern devices.
Timeline (last 90 days)
ECDSA (Elliptic Curve Digital Signature Algorithm) is a digital signature standard based on elliptic curve cryptography (ECC), widely used in scenarios such as TLS certificates, blockchains, and secure boot.
Jailbreak firmware typically requires disabling or bypassing the secure boot chain and the trusted execution environment (TEE); once secure boot is broken, malware can persist with the highest privileges.
Under a secure boot mechanism, even if an attacker modifies the firmware code, as long as the private key is not leaked, the modified firmware cannot pass signature verification.
