Secure File Explorer – slExplorer

Abstract

Mobile phone devices are a key component of our daily life. Owner of the device carries their personal information, financial data and many other sensitive files in their mobile devices. If an attacker steals your mobile phone then he/she can easily extract secret information from it. The file explorer has the access to pictures, music, videos, documents, and other files on your Android devices. It also allows sharing files with other android users or internet applications. In this project, we are planning to develop a secure file explorer which will not only protect the local files but also provides a secure channel to share these files. In order to design slExplorer, we will consider local authentication, peer authentication and establishment of secure channel. slExplorer allows users to protect their file through passwords. The files are then encrypted with these passwords and stored in local storage. The users can decrypt and view files only when the correct password is entered. A password manager manages the passwords related to each file. The file is shared through online repository i.e. Dropbox using asymmetric cryptography.
