Abstract
Data transaction in internet of vehicles is a transaction occurs between vehicle owner and data buyer. Blockchain is a new technology that brings decentralized ledger system for user, which means users could make payment without the third party. There are several projects combined internet of vehicles and Blockchain, however, none of them realize a trustworthy anonymous data transaction. In this paper, we first propose the concept of Super Nodes to guarantee data authenticity, then we construct the anonymity for the transaction base on zero-knowledge Succinct Non-interactive Argument of knowledge (zk-SNARKs) and DAP from Zerocash. Moreover, a smart contract is deployed for mutual benefits. Simulation experiment shows this scheme is practical.
Supported by the construct program of applied characteristic discipline in Hunan University of Science and Engineering.

Notes
- 1.
Negligible function.
- 2.
\( {\text{PRF}}\left( {} \right) \) is a pseudorandom function.
- 3.
\( {\text{COMM}}\left( {} \right) \) is a statistically-hiding non-interactive commitment scheme, which satisfy the verifiability: given \( c{\text{ := COMM}}_{r} \left( s \right) \), one who knows r and s can verify that \( {\text{COMM}}_{r} \left( s \right) \) is equal to \( c \).
