Abstract: as cloud computing provides storing and sharing records via a cloud service because of on demand resource access and elasticity. For secure record sharing requires encryption of records before outsourcing. Key management system is one of the important aspects of the system. For sharing large number of documents, each record needs to be encrypted using different keys. Since to decrypt these records requires all keys which is very different task. Hence this approach uses aggregated key system, which aggregates all the keys. Later at the time of decryption of all records it requires one aggregated key. Considering large number of records in the cloud. For the efficient access of these records, it is necessary to search for the records over encrypted file. For this purpose , required to build for the index file. Multi keyword entries searches for the relevance record by matching keywords with the index file
