Aggregation function using Homomorphic encryption in participating sensing application

Participatory Sensing Application is new emerging computing paradigm that uses the data collected by the participants via mobile devices and active sensors. It gives an opportunity with the help of increasing number of mobile users to share information acquired by their sensor equipped devices. However, security and privacy are the major concerns in the success of these applications. While several security implementation techniques have discussed by the research community, one of them is Homomorphic encryption that allows aggregating encrypted values and the result would be same as unencrypted data. In this paper, we simulate the aggregation function using homomorphic encryption in participating sensing application.
