This paper presents a new method for generating group digital signatures. Because of the importance of digital signatures in electronic management of business’s documents, it is important to develop strong methods to enhance and authenticate business’s documents in electronic environment, especially in sensitive applications. Existing methods normally implement asynchronous encryption algorithms like RSA for producing such digital signatures but we extent the approach by introducing the concept of document’s context in order to group selected authenticated users to each context type. This scheme uses alternative steps for signing sensitive documents by classifying data according to their sensitivity such as classified, secrete, or top secret data. The main property of this scheme is that the group signature is a combination of message group and context group signatures. Finally, this scheme generates group signatures with multiple public keys corresponding to group members instead of one public key for each group implemented in most other group signatures schemes.
