Security issues in an EDI environment

EDI (Electronic Data Interchange) means electronic transmission, processing, and storage of commercial, business, or trade related documents. The paper surveys the security threats posed to an EDI system, and outlines the techniques and services used to counter these threats. Most importantly, the paper has gone into great depth to address an EDI specific security requirement-non repudiation of receipt. The current related work done to support this service is first discussed, and then a new and simple, but effective protocol to achieve non repudiation of receipt on a distributed and heterogeneous system platform is proposed
