Zeroization Protocols

Zeroization protocols are defined procedures for the immediate and irreversible erasure of sensitive information from a device, typically triggered by a security violation. In hardware security modules, this is the final line of defense; if the device detects tampering, such as a physical breach or voltage attack, it destroys the stored keys.

This ensures that even if an attacker gains physical control, they cannot access the secrets inside. These protocols must be carefully designed to be fast and reliable, ensuring that no traces of the data remain in the memory cells.

They are critical for the security of institutional custodians who manage billions in assets, providing peace of mind that keys cannot be extracted through physical means. It is a fundamental component of tamper-responsive system design.
