Privacy Preserving Data Aggregating With Multiple Access Channel

The authors consider the scenario in which a set of users want to compute an aggregate function of their messages at a message center. The users communicate with the message center over a multiple access channel with fading, where the fading states of the channels from individual receivers are unknown a priori to the message center. For privacy reasons, the users do not want disclose their message information to the message center. No computational limitations on the message center are assumed, and the message center may collude with a set of hidden eavesdroppers to retrieve the message information of the users.
