The invention discloses a satellite navigation chip integrated with a data safety function. The chip comprises an RF module, a navigation baseband module, a power supply module, a processor and a safety module, wherein the processor determines whether information needs encryption or decryption, sends information which needs safety setting to the safety module, and sends out information received from the safety module; and the safety module encrypts or decrypts the information which needs safety setting according to a set safety manner. The invention also discloses an application method of the satellite navigation chip integrated with the data safety function. According to the chip and the application method thereof, the received information can be encrypted or decrypted, and the safety of data transmission is improved.
Description
technical field [0001] The invention relates to the field of information security for satellite navigation applications, in particular to a satellite navigation chip with integrated data security functions and an application method thereof. Background technique [0002] With the construction of the global satellite navigation and positioning system, various related applications have also emerged, and satellite positioning is one of them. To achieve satellite positioning, satellite navigation chips are an indispensable part. Satellite navigation chips capture / track satellite signals and provide accurate user location information, which is the basis for the application of three-dimensional positioning information. However, there are great hidden dangers in the transmission of these positioning information. With the increasing demand for information security, The development of a satellite navigation chip that can encrypt positioning information has become a must for some secu...
