中文摘要： 由于数据融合要求节点进行内网处理，传统链路加密和认证技术不能直接为数据融合协议提供机密性和完整性保护。本项目针对节点能量受限、节点容易被俘获、链路容易被控制等特点，研究无线传感器网络安全数据融合协议，在降低通信代价以节省节点能量和增加网络寿命同时，确保采集数据和融合数据的机密性和完整性，具有重要的理论意义和应用价值。本项目拟研究基于信任的完整性保护数据融合协议主动防范被俘获节点对最终融合结果的影响；研究面向端到端机密性保护数据融合协议的ID列表检测算法和可分离同态加密算法，解决ID列表传输能量消耗和多维数据安全融合问题；研究基于可分离同态加密算法和融合消息认证码的同时具有机密性保护和完整性保护的安全数据融合协议；实现本项目提出的各种协议，构建原型系统。本项目拟从理论到实践完整地研究无线传感器网络安全数据融合问题，可发表SCI/EI检索论文12~16 篇、申请发明专利6项、软件著作权2项。

英文摘要： Traditional link encryption and authentication technology cannot directly ensure confidentiality and integrity for aggregation protocol because of in-network aggregation. Moreover, in wireless sensor networks, sensor nodes usually have limited energy, and both nodes and links are vulnerable to be compromised and controlled. Addressing these issues, this project aims to provide effective secure data aggregation protocols for wireless sensor networks. The project is valuable both theoretically and practically since it can guarantee data confidentiality and integrity with the prolonged network's life, which is achieved by reduced communication for energy saving of nodes. This research includes: (1) Studying trust-based integrity-preserving data aggregation protocol to actively prevent compromised node from affecting aggregation result; (2) Researching ID-list detecting algorithm and separable homomorphic algorithm for end-to-end confidentiality-preserving data aggregation protocol, to resolve the energy consumption problem in ID-list transmission and the security challenges in multi-dimension data aggregation; (3) Introducing confidentiality-preserving and integrity-preserving data aggregation protocol based on separable homomorphic encryption algorithm and aggregate message authentication code; (4) Implementing th
