The cloud computing is getting more and more important due to the large size of files that need to be shared and cannot be sent through the email. The need for cloud computing create a new challenges for security. In Cloud computing, there are three main parties: the server, the client, and the channel of transfer. The security of the first two parties is manageable. However, the security of the channel cannot be guaranteed due to possible intruders. This paper presents an idea that makes the cloud environment more secure. The authors' approach is based on a technique where the client data split his data into two un-readable files, and uploads them to cloud server.
