    The emergence of mobile P2P systems is largely due to the
    evolution of mobile devices into powerful information
    processing units. The relatively structured context that
    results from the mapping of mobile patterns of behaviour
    onto P2P models is however constrained by the
    vulnerabilities of P2P networks and the inherent limitations
    of mobile devices. Whilst the implementation of P2P
    models gives rise to security and reliability issues, the
    deployment of mobile devices is subject to efficiency
    constraints. This paper presents the development and
    deployment of a mobile P2P system based on distributed
    hash tables (DHT). The secure, reliable and efficient
    dispersal of files is taken as an application. Reliability was
    addressed by providing two methods for file dispersal:
    replication and erasure coding. Security constraints were
    catered for by incorporating an authentication mechanism
    and three encryption schemes. Lightweight versions of
    various algorithms were selected in order to attend to
    efficiency requirements.
