Location Privacy against Traffic Analysis Attacks
نویسندگان
چکیده
We propose a method which provides location privacy against traffic analysis attacks. Traffic analysis is the process of intercepting and examining messages in order to deduce information from patterns in communication. It can be described as the passive attacks that try to deduce the traffic pattern based on the eavesdropped information. They launch an active attack according to the achieved information about the nodes and synchronizing the cooperation of distributed components. Base station location privacy is the important term that is combined with two important concepts defined above .The proposed location privacy method is designed in order to remove the local adversary effect, sinkhole attack and Sybil attack. The network mix ring concept helps in local adversary effect while we have designed mobile sinks against sink hole attack. The Sybil attack is prevented by the trust value computing. In this paper we present our proposed technique with the small experimental setup that helps in further simulation of the technique. General Terms Design, Security, Experimentation

Location Privacy Issues in Wireless Sensor Networks
We discuss location privacy issues in wireless sensor networks. We consider sensor nodes with more responsible roles and the need to protect locations of such nodes. Available countermeasures against various types of traffic analysis attacks are examined and their problems are identified. We do not propose new traffic analysis resistance technique. Instead, we draw attention to blanks in curren...
متن کاملProbabilistic receiver-location privacy protection in wireless sensor networks
Wireless sensor networks (WSNs) are continually exposed to many types of attacks. Among these, the attacks targeted at the base station are the most devastating ones since this essential device processes and analyses all traffic generated in the network. Moreover, this feature can be exploited by a passive adversary to determine its location based on traffic analysis. This receiverlocation priv...
متن کاملImproving Tor security against timing and traffic analysis attacks with fair randomization
The Tor network is probably one of the most popular online anonymity systems in the world. It has been built based on the volunteer relays from all around the world. It has a strong scientific basis which is structured very well to work in low latency mode that makes it suitable for tasks such as web browsing. Despite the advantages, the low latency also makes Tor insecure against timing and tr...
متن کاملProtecting source-location privacy based on multirings in wireless sensor networks
Wireless sensor networks (WSNs) are expected to be widely deployed to collect data in military and civilian applications. Because of the open nature of WSNs, it is easy for an adversary to eavesdrop sensor communication and to trace packets, causing privacy concern for the sensor devices. The privacy issue, especially location privacy, can be critical for monitoring applications in WSNs. A uniq...
متن کاملPAS-MC: Privacy-preserving Analytics Stream for the Mobile Cloud
In today’s digital world, personal data is being continuously collected and analyzed without data owners’ consent and choice. As data owners constantly generate data on their personal devices, the tension of storing private data on their own devices yet allowing third party analysts to perform aggregate analytics yields an interesting dilemma. This paper introduces PAS-MC, the first practical p...
