| Outline of Research at the Start |
After disasters, governmental and non-governmental organizations collaborate on disaster relief activities. Therefore, information sharing among different organizations is necessary and critical for their collaboration. Many existing works use traditional databases to store shared data, but they perform poorly in disaster environment because of single-node failure and low security. We propose to use blockchain to enable decentralized information sharing with low-cost, high security and strong flexibility.
|
| Outline of Final Research Achievements |
The goal of this research is to develop a resilient blockchain system for secure information sharing in disaster environment. We propose to use blockchain to enable decentralized information sharing with low-cost, high security and strong flexibility. To address special challenges of disaster environment, we further enhance existing blockchain techniques by developing many new features, e.g., resilient consensus protocols and light-weight blockchain nodes. The research results have been published in top international journals (e.g., IEEE TETC and IEEE JSAC) and conferences (e.g., IEEE INFOCOM).
