PCPP: Private Computing on Public Platforms A New Paradigm in Public Computing

As cellular telephones and high capacity memory sticks emerge as users´ primary repository for data and applications, users will often run applications and display data on remote hosts. The biggest challenge in supporting this mobile data, mobile applications, stationary platforms model is in ensuring security of the applications as well as the platforms. To that end, we propose PCPP as a new paradigm in public computing in which the remote host is not trusted, rather, security is owned and enforced by the application. PCPP is a two step process which ensures that the application running on the remote host remains unaltered, unmonitored, and unrecorded for future analysis by the public platform or any application running on the public platform
