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.

Abstract: A wireless mesh network includes several mesh networks and the wireless mesh network access points to which the mesh networks belong. A method establishing backbone routing and network tolopogy among each wireless mesh network access points, selecting one said wireless mesh network access point as a location inquiry sever for all the mesh networks, and acquiring the corresponding relations between all the mesh networks in the wireless mesh network and the wireless mesh network access points to which the mesh networks belong. When said mesh network needs to transmit data, the access point inquires the location inquiry server for the wireless mesh network access point which the destination mesh network belongs to, and performs routing based on the network topology.
