Abstract: Systems and techniques for tamper detection of electronic devices are described. The tamper detection is performed using a tamper circuit that includes an authenticator connected to an auxiliary power source of the electronic device via a switch. The switch is configured to open and break the connection between the authenticator and the auxiliary power source when a housing of the electronic device is opened or tampered with. The authenticator may be evaluated, and a value compared against a server-based value to determine a difference in values and thereby detect tampering.
