Securing Files in the Cloud

Dropbox, Google Drive, OneDrive, Box etc are popular File Storage providers for the Cloud. Recently reported vulnerability like Heartbleed for servers using OpenSSL has created panic among Cloud users. Hence, it is essential to encrypt the files by the users before uploading them to the cloud. Many File encrypting tools like Veracrypt, AxCrypt, Boxcrypt, are in place to encrypt files. But they have implemented AES and RSA encryption algorithm which are not secure against quantum computing. In this paper, we have implemented a lattice based encryption algorithm based on hardness of Ring LWE problem, which is secure against quantum computing to secure files stored in Cloud Storage.
