Abstract: A storage device for data encryption and self-destruction includes a controller, an interface module, a storage module, an encryption and authentication module, a positioning module, a power supply module, and a communication and self-destruction module. The interface module, the storage module, the encryption and authentication module, the positioning module and the communication and self-destruction module are electrically connected to the controller, respectively. The encryption and authentication module is configured to encrypt and protect data stored in the storage module, and authenticate a request for remote access to the storage device. The communication and self-destruction module is configured to send position information acquired by the positioning module to a storage device management system, receive and execute a data destruction instruction issued by the storage device management system, and destruct the data stored in the storage module. The power supply module is configured to provide electrical energy for the storage device.

Abstract: An anti-spoofing satellite navigation and positioning method includes: receiving a positioning satellite radio frequency (RF) signal by a satellite RF receiving module, and detecting whether a power strength of the received signal exceeds a preset threshold; preprocessing the received signal by a satellite RF signal identification module, and intercepting an identifiable positioning satellite signal for identification to distinguish a real signal and a false signal; calculating the received signal to acquire real position and time information when the received signal is identified as the real signal; and sending an alarm message when the received signal is identified as the false signal. An anti-spoofing satellite navigation and positioning chip is further provided. By identifying whether the signal is a real signal or a false signal, the authenticity of the upper-layer position calculation is ensured, and the purpose of timely and accurate detection and effective resistance to spoofing attacks is achieved.
