One of your clients; the National Meteorological Services (NMS) offers in-depth weather forecasting services to airlines, trucking firms, event planners, and other organizations that need the latest and most accurate weather forecasting services. NMS has discovered that their forecast information, which was being sent out as email attachments to its customers, was being freely distributed without NMSs permission, and in some instances, was being resold or even falsified by their competitors.

NMS wants to look into encrypting these weather forecast documents to provide confidentiality. In addition, the company also wants to provide to their customers a level of assurance that these documents originate from NMS and have not been tampered with.
