A tamper-proof structure and an electronic device are provided in the present application. The tamper-proof structure includes a first-order circuit board, at least one tamper-proof component, at least one safety signal wire and a security chip. The safety signal wire is wrapped around an outer layer of the first-order circuit board or penetrates through a through hole and is wrapped around an inner layer of the first-order circuit board to form a tamper-proof area as required. The safety signal wire is connected to a tamper-proof switch and the security chip correspondingly, and a level of the safety signal wire is changed when the tamper-proof switch or the safety signal wire is damaged, and the security chip is triggered to erase sensitive information accordingly. By punching on the first-order circuit board, an objective of tamper-proof and an objective of reduction of design cost and simplification of security solution are achieved simultaneously.

Tamper-proof structure and electronic device

A secured payment method, secured payment device and computer-readable storage medium, relating to the technical field of Internet. The method comprises: detecting whether a mobile terminal is connected to a first secured payment module, wherein the first secured payment module shares a payment hardware interface with the mobile terminal; activating the payment hardware interface, if the detection result shows that the mobile terminal is connected to the first secured payment module; detecting whether the payment hardware interface is controlled by the first secured payment module or by the mobile terminal; providing a payment warning, if the detection result shows that the payment hardware interface is controlled by the mobile terminal. Thus, the manufacturing costs of the devices can be reduced, potential safety risk in some transaction can also be avoided, and a secured payment is guaranteed.

Secured payment method, secured payment device, and computer-readable storage medium

A sensitive element protection mechanism and a payment device using the sensitive element protection mechanism includes a circuit board; a sensitive element configured for storing, transmitting and/or processing user account information and user transaction information; a shield arranged in parallel with the circuit board; and an elastic member connecting the circuit board and the shield. The sensitive element is located on a side of the circuit board near the shield. The circuit board and the shield are provided and the sensitive element is provided between the circuit board and the shield so as to protect the sensitive element through the shield. The elastic member connects the circuit board and the shield to prevent the circuit board from being separated from the shield, thus preventing the circuit board from being opened to steal sensitive information in the sensitive element.

Sensitive element protection mechanism and payment device

A hardware encryption housing and a payment device using the hardware encryption housing includes a top shell, a bottom shell, a circuit board and a trigger switch configured to transmit a trigger signal when the top shell is separated from the bottom shell. A security chip, mounted on the circuit board, has a storage module configured to store key information and a detection module configured to clear the key information and lock the security chip after the trigger signal is detected. The trigger signal is transmitted when the top shell is separated from the bottom shell, and the detection module is provided in the security chip to detect whether the trigger switch transmits a trigger signal. When detected, the key information in the storage module is cleared and the security chip is locked.
