Abstract: The dual signature is a new application of digital signature in SET protocol. It resolves security correspondence of the consumer, business and bank in electronic transaction. This paper analyzes the dual signature technology, puts forward a design project of dual signature presentation experiment, and realizes it by using the developing tool C# based on cryptography model of .NET framework.
