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.

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.
