Efficient non-interactive anonymous communication

Publikasjonsdetaljer

Methods for untraceable and anonymous communication, such as anonymous routing networks and dining cryptographers networks, are in general very complex and suffer from high performance overhead of a minimum order of
encryptions for N participants. In this paper, we propose an original approach to untraceable communication that avoids some of the significant shortcomings of existing methods. Using non-interactive privacy-preserving aggregation as an underlying building block we achieve attractive features, including unsurpassed low computational and transmission overhead of only 3 encryptions per participant in only a single round.
