Cloud computing is a model for enabling convenient on request network access to a shared and configurable computing resources such as networks, servers, storage, applications and that can be frequently provisioned and released with minimal management effort or service provider interaction. In cloud computing more amount of data store in the cloud such software, hardware, etc. The main issue is providing security and frequent verification of files. In this paper, the authors proposed batch auditing framework which audit multiple data owner's files simultaneously. They used polyalphabetic ciphers to encrypt files of data owners and for secure message passing to owner they used simple mail transfer protocol.
