Abstract: Staying anonymous and not revealing real identity is highly desired in today's mobile business. Especially generic frameworks for different kinds of context-aware mobile business applications should provide communication anonymity of mobile users as a core security feature. For enabling communication anonymity, Mix-net based solutions are widely accepted and used. But directly deploying existing Mix-net clients on mobile devices with limited hardware capacity is not a realistic approach. In addition, different anonymity sensitivities of both applications and users require to enforce anonymity dynamically rather than on a fixed level. In this paper, we present an approach towards a solution that addresses the specific anonymity challenges in mobile business while exploiting the benefits of existing Mix-net frameworks.
