Performance Analysis of Client Side Encryption Tools

Client side encryption tools are becoming popular among cloud users to increase the security of their data stored in the cloud server. Several client side encryption tools have been already introduced with their own features and security schemes. It is necessary for users to find out the best tool for encrypting data and storing it in the cloud. “Which one provides more security from those tools? Which one consumes less time? In a word, which one is the best?” These are the open questions to the users, now-a-days. To find out the best tool, we have analyzed the performance of the selected tools namely Boxcryptor, Ensafer, SharedSafe, SafeMonk and Cloudfogger. To measure the performance, we have calculated the upload time (encryption and synchronization time) for different sizes of data for each tool. Comparing the performance among these tools, we have obtained the best tool.
