Intrusion tolerance schemes to facilitate mobile e-commerce

In this paper, we concentrate on one aspect of information system security, namely that of intrusion tolerance. An intrusion tolerant system is one that continues to function correctly and provide the intended user services in a timely manner even in the face of an information attack. In this paper we concentrate on a technique called fragmentation-redundancy-scattering and investigate how this technique can be used in a mobile environment. We also provide different schemes towards ensuring intrusion tolerance in a mobile system.
