WebShamir secret sharing technique is used for the creation of data for repairing. The parameters are selected such that as many shares as possible should be generated for good quality reconstruction. The new scheme guarantees, no matter what type of attack, at least some shares must survive it and hence the actual data can be reconstructed. WebSecret Sharing . Vijaya lakshmi Pandranki ,N.Krishna . Abstract— Group key establishment is an important mechanism to construct a common session key for group communications. Key transfer protocols rely on a mutually trusted key generation center (KGC) to select session keys and transport session keys to all communication entities secretly.
