Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0026] Such as figure 1 As shown, an O2 encryption embedded solution for the positioning module, this solution reuses the baseband and control chip in the original positioning module (GNSS Module), and designs a separate microcontroller (MCU), as the new positioning module The external interface chip, the microcontroller is also connected with a memory (EEPROM), and is connected to the power supply module (Powersupply Module) through the power interface, and leads to the transceiver interface and data interface at the same time. On a separate microcontroller, read the original positioning data, implement the O2 encryption algorithm that meets the...

Abstract

An O2 encryption embedded solution for a positioning module includes the steps of S1, initializing hardware equipment; S2, searching available satellites, and entering the next step if the satellite number is greater than the minimal number of available satellites within the predetermined time, otherwise, conducting abnormal processing; S3, obtaining and parsing satellite messages to obtain original positioning data; S4, conducting O2 encryption operation for the original positioning data; S5. deflection positioning data packets after the O2 encryption operation is performed, and S6, sending the data packets back to step S3. Rapid transformation in traditional embedded products is realized without changing the original software and hardware design, and plug and play O2 encryption function can be rapidly and transparently introduced by packing and designing O2 encryption function. The problems of great change, long period, high cost and instable quality caused by achieving O2 encryption function in a conventional embedded system can be solved, and new solution is provided for promoting and popularizing O2 encryption.

Description

technical field [0001] The invention relates to a positioning encryption method, in particular to an O2 encryption embedded solution of a positioning module. Background technique [0002] With the rapid development of the Internet of Vehicles industry, its related technologies have been widely used in the automotive electronics industry and have been applied to various fields; Interconnection of information between people. Cars are no longer a simple means of transportation, but have gradually developed into an important part of intelligent travel and vehicle data collection. [0003] The positioning function is an important basic service of the Internet of Vehicles. In order to meet the requirements of high-precision positioning and ensure the security of geographic location information, the state has formulated the O2 encryption algorithm specification, which is a method of deflecting the original data of location information through a confidential plug-in according to t...
