An Efficient Data Sharing Scheme for Privacy Protection Based on Blockchain and Edge Intelligence in 6G-VANET

Table 1

Comparison of research literatures.

Research literatures	Advantages	Disadvantages
Data sharing [12–21]	Ensure the security of data storage and improve storage efficiency through various technologies.	The correctness and repeatability of the data itself cannot be guaranteed.
Privacy protection [22–26]	Through various technologies, the privacy of each participant is protected, and the information security of users is guaranteed.	The actual implementation process is too expensive and is not suitable for large-scale VANET.
Application of blockchain in VANET [5, 6, 27–31]	The sensitive information in VANET is stored in the blockchain, which improves the safety of users during driving.	The consensus process of the blockchain used is inappropriate and cumbersome.
