Summary Groups can be formed as a fixed or static set or as a varying or dynamic set. Previously, no researcher considered groups, other than the two configurations. Yet, a new method is the formation of groups and the signatures, based on demand approach, which non trivializes the issue. By considering groups as virtual, issues of scalability, revocation rights of members, memory area for storage of private key for each member, etc, are addressed. The dynamic characteristics of private key, public key, partial signatures of individual members, as well as the group as an entity are factors. The generation of signatures by a group member is with its private key and the groups partial signature. This arrangement facilitates many advantages such as scalability, revocation, tracing, man‐ in‐the‐middle attacks, space requirements, and multiple keys of the group members. Even so, the procedure is adaptable for cloud computing, group communication as in banks to access group accounts with group signatures, group mobile communication, etc. This framework automates the banking system completely.
