而直接的基于同态加密的方案对于节点被俘获的情况也无能为力
) 摘要: 在无人值守的无线传感器网络(unattended wireless sensor networks)中
因此必须保证数据在传输过程中的保密性和完整性
collector’s retrieval results, data are aggregated along being forwarded
The data confidentiality and integrity should be protected at the intermediate nodes
End-to-end encryption or hop-by-hop encryption based schemes are not efficient
Straightforward homomorphic encryption based scheme is not compromise resilient
To achieve all the desires, we propose a scheme - H2S by making use of both homomorphic secret sharing and homomorphic encryption
The security and efficiency of our scheme are justified by extensive analysis

又要确保数据传输的有效性
数据在传输时往往会在一个汇聚点(aggregator)聚集起来
为了让数据有效的传输
提出了一种 H2S(Homomorphic encryption and homomorphic secret sharing)的方案
基于端到端的加密(end-to-end encryption)和逐跳式的加密(hop-by-hop encryption)的方案往往不能解决问题
我们综合运用同态秘密共享和同态加密这两种方法
