Table 3 Current problems and solutions for improved scheme
From: IoV data sharing scheme based on the hybrid architecture of blockchain and cloud-edge computing
Type | Problems | Solutions for Improved Scheme |
|---|---|---|
Privacy Security | Tamperable, Data Leakage, Hacker Attack | The underlying architecture based on blockchain is adopted to ensure data security by taking advantage of the decentralized and non tampering characteristics of blockchain; The malicious nodes are effectively filtered |
Data Storage | Accessibility, Large scale data storage, Small block capacity | The data is stored in edge devices, which realizes the storage and convenient access of large-scale data |
Efficiency | Delay, Waste computing resources | Adopt double chain structure to improve work efficiency; Reduced resource waste compared to pow |
