example 1

[0067] After the vehicle-mounted terminal and the remote server subscribe to content (such as sports news) through the app, the specific method of updating the key is as follows:

[0068] Firstly, obtain the interactive information related to the sports news content subscription from the vehicle terminal, including subscription number TY123456, subscription time 20190430 (date) or 201904301200 (date + time), location coordinates 100200 (XY value in the map), from the remote server Obtain interactive information related to subscription of sports news content this time, including subscription type TYFREE (sports free), app information TYvideo01 (app name and number).

[0069] Secondly, the current interaction parameters are extracted from the above information: (TY123456, TYFREE, 20190430, 100200, TYvideo01). At the same time, read the historical interaction parameter 1 (TY123700, TYFREE, 20190310, 100200, TYvideo02), parameter 2 (TY232728, TYFREE, 20190425, 123345, TYvideo01), ...

Abstract

The invention relates to a key updating system for vehicle-mounted equipment interaction. The system extracts a plurality of current interaction parameters from interaction information, compares eachof the plurality of current interaction parameters with a corresponding parameter in a plurality of historical interaction parameters, calculates an interaction key through the plurality of current interaction parameters obtained after comparison, and generates a new interaction key. The invention further provides a secret key updating method for vehicle-mounted equipment interaction, the secret key is generated by using the vehicle-mounted equipment interaction information, the complexity of the secret key can be increased, the use condition of the vehicle-mounted equipment can be monitored in real time according to the user interaction statistical information, the secret key is updated in time, and the safety of the whole system is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle system encryption, in particular to a key update system for vehicle device interaction. Background technique [0002] Data encryption technology is the core technology of Internet of Vehicles security, especially in today's era of rapid rise of various network services such as e-commerce, digital currency, and online banking, how to protect data security from being stolen, tampered with or destroyed More and more people pay more and more attention to these problems, and the key to solving these problems is data encryption technology. [0003] The so-called encryption is the process of converting "plaintext" readable data into "ciphertext"; and decryption is the process of restoring "ciphertext" to "plaintext". Encryption and decryption must be implemented using cryptographic algorithms. Usually, the more complex the algorithm, the more secure the ciphertext. In various symmetric encryption algor...
