AbstractEmerging connected devices lead to ubiquitous communication in which anonymity and efficiency gain additional importance. In this paper, we show that current measures for sender anonymity are not sufficient and propose a new approach based on DCnets. The novel ADCnet mechanism establishes local DCnet groups that communicate asymmetrically and hide senders with lower communication overhead in comparison to cover traffic-based anonymization and classical DCnets. This paper presents concepts for the initialization and the group formation of ADCnets. The novel mechanism of ADCnets is evaluated w.r.t. anonymity and efficiency. We show that ADCnets provide DCnet-like anonymity while massively improving efficiency.
