Research on Internet of Vehicles' Privacy Protection Based on Tamper-Proof with Ciphertext

摘要

With the development of the internet of vehicles, the safety of the wireless network communication in the internet of vehicles and the privacy protection of users are in need of an immediate solution. In order to address the interception and tampering by an attacker of the contents among the vehicle mobile terminals, and their consequence of the privacy leakage of the location, and the user's activity tracks and also the consequence of the user's receiving the wrong information due to the tampering of the message, this essay comes up with a solution of tamper-proof ciphertext of the revised ciphertext policy attribute-based encryption, which to some degree has reduced the risk of the leakage of the user's information. This solution realize the encryption protection of the contents of the vehicle mobile terminals by destroying the structure extension of the ciphertext, achieves the goal of non-extensibility security.
