Scalable and secure group key agreement for wireless ad-hoc networks by extending RSA scheme

摘要

Groups can be formed as a fixed or static set or as a varying or dynamic set. Previously, noresearcher considered groups, other than the two configurations. Yet, a new method is the formationof groups and the signatures, based on demand approach, which non trivializes the issue. Byconsidering groups as virtual, issues of scalability, revocation rights of members, memory area forstorage of private key for each member, etc, are addressed. The dynamic characteristics of privatekey, 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 partialsignature. This arrangement facilitates many advantages such as scalability, revocation, tracing,man-in-the-middle attacks, space requirements, andmultiple keys of the groupmembers.Evenso,the procedure is adaptable for cloud computing, group communication as in banks to access groupaccountswith group signatures, group mobile communication, etc. This frameworkautomates thebanking system completely.
