Abstract：Unattended Wireless Sensor Network (UWSN) is usually deployed in a bad or hostile environment. The deployment of static aggregation node (or base station) is difficult, making real-time information aggregation impossible. Hence the node should undertake the mission of self-sustaining the data temporarily. In order to enhance the probability of data survival, this paper proposed a dependable data survival scheme based on Chinese Remainder Theorem (CRT) weighted threshold secret sharing in UWSN. The scheme built a node reputation model in the network, improving the efficiency and effectiveness of key division, distribution and reconstruction. In addition, this paper also discussed the good homomorphism properties of CRT based multi-secret sharing, and the key combination operation scheme, which further ensures the reliable survival of data.
