Antitamper and hardware protection mechanisms
Tamper resistance means using specialized components to protect against tampering with a given device. One of the common and effective ways of implementing antitampering, which can strengthen the hardware security of a device, is by adding tamper detection switches, sensors, or circuitry in the device, which can detect certain actions such as the opening of the device or its forceful breakage, and would act based on that by deleting the flash memory, or making the device unusable.
Along with this, it is highly recommended to protect sensitive chips and components by removing their labels, hiding them with epoxy, and even encapsulating the chips in a secure enclosure.
Some other techniques of implementing tamper resistance include incorporating tight airflow channels, security screws and hardened steel enclosures-all of which would make tampering with the device extremely difficult.
