It is nonetheless desirable to reliably compute the social distance among individuals. This must be done anonymously, without giving away any identifying information about individuals in the social network, and reliably, without allowing anyone to pretend to be socially closer to someone else than they actually are. The Social Network Connectivity Algorithm, or SoNCA, ac- complishes these goals in a distributed manner. This paper describes both the high-level algorithm and a concrete design that is intended for future use with a network, AllNet, designed to provide secure interpersonal communication utilizing all avail- able means, including Internet, cellular communications, ad-hoc networking and delay-tolerant networking.4en-USCC-BY-SAComputer sciencesocial networkComputer scienceAd hoc networks (Computer networks)Ad hoc networks(Computer networks)Conference Paper
