Resilient and Secure File Dispersal in a Mobile P2P System

The convergence of mobile networks and P2P systems has led to the deployment of a range of schemes for file storage over a network. This paper presents an approach to resilient file management and network storage through the design and implementation of a file dispersal system for a mobile P2P network, based on distributed hash tables (DHT). Inherent issues of security, reliability and efficiency are addressed by integrating two forms of data redundancy, pure replication and erasure coding. The functionality of the system and its configuration were enhanced at different levels by a variety of security-related techniques. Experimental results on the different stages of the file dispersal process were provided as validation of the proposed system.
