摘要：The increasing capabilities of mobile devices have given raise to many mobile sensing applications. Theproblem with existing system of the mobile sensing applications is that the sensor data aggregation assume a trustedaggregator, and hence cannot protect user privacy against untrusted aggregator. An untrusted aggregator in mobilesensing can periodically obtain desired statistics over the data contributed by multiple mobile users, withoutcompromising the privacy of each user. To address this problem, we propose an efficient protocol to obtain the Sumaggregate, which employs an additive homomorphic encryption and a novel key management technique. Evaluationsshow that our protocols are orders of magnitude faster than existing solutions, and it has much lower communicationoverhead.
