	1	Secure Two-Party Distance Computation Protocol Based on Privacy Homomorphism and Scalar Product in Wireless Sensor Networks显示文摘Numerous privacy-preserving issues have emerged along with the fast development of the Internet of Things. In addressing privacy protection problems in Wireless Sensor Networks(WSN), secure multi-party computation is considered vital, where obtaining the Euclidian distance between two nodes with no disclosure of either side's secrets has become the focus of location-privacy-related applications. This paper proposes a novel Privacy-Preserving Scalar Product Protocol(PPSPP) for wireless sensor networks. Based on PPSPP, we then propose a Homomorphic-Encryption-based Euclidean Distance Protocol(HEEDP) without third parties. This protocol can achieve secure distance computation between two sensor nodes. Correctness proofs of PPSPP and HEEDP are provided, followed by security validation and analysis. Performance evaluations via comparisons among similar protocols demonstrate that HEEDP is superior; it is most efficient in terms of both communication and computation on a wide range of data types, especially in wireless sensor networks.

	2	Cooperative Secrecy to Resist Authentication Error in Two-Hop Wireless Networks显示文摘The authentication error in two-hop wireless networks is considered without knowledge of eavesdropper channels and location.The wireless informationtheoretic security has attracted considerable attention recently.A prerequisite for available works is the precise distinction between legitimate nodes and eavesdroppers.However it is unrealistic in the wireless environment.Error is always existing in the node authentication process.Best of our knowledge,there are no works focus on solving this problem in the information-theoretic security.This paper presents a eavesdropper model with authentication error and two eavesdropping ways.Then,the number of eavesdroppers can be tolerated is analyzed while the desired secrecy is achieved with high probability in the limit of a large number of relay nodes.Final,we draw two conclusions for authentication error:1) The impersonate nodes are chosen as relay is the dominant factor of the transmitted message leakage,and the impersonation attack does seriously decrease the number of eavesdroppers can be tolerated.2) The error authentication to legitimate nodes is almost no effect on the number of eavesdroppers can be tolerated.
