Trapdoor Reduction on Sharing Group Data in Cloud using Aggregation Key Scheme

In cloud environment, number of clouds storage are available and these functional part of data storing, data sharing on huge number of space available for data storing that’s why number of organization are move towards the cloud system for the use of data store. In Aggregation Key Scheme, data owner is work for uploading & sharing data with multiple user at a time. Data leaks in cloud environment and that their common approach is occurring encrypt with all data before uploading to cloud and also the encrypted data will convert into decrypted by the used of aggregation keys. For designing and implementing general framework of Aggregation Key Method with seven different algorithms for providing security analysis parameter like setup phase, key generation phase, encryption phase, key extraction phase, trapdoor generation phase, trapdoor adjustment phase and trapdoor testing phase. The publicly cloud is always used to sharing some confidential industrial or business data. (Examples- Drop box, Open drive, Google Drive, etc.) The main goal of Aggregation Key scheme is to reduce trapdoor. If user occurring any type issue or query over shared data by multiple owners then he must generating multiple trapdoor to the cloud environment and these numbers of trapdoors under multi-owners setting destroy the way of Trapdoor by using RSA Trapdoor algorithm.
