AccessĪccessing a volume is always done using a piece of information known as a share. Links identify an entry’s position in the folder tree, and nodes contain the entry’s metadata. In the case of files, the associated node also references the file content, which is split into multiple blocks, each with a maximum size of 4 MB. This model, similar to the Portable Operating System Interface (POSIX) file system model, facilitates communication and synchronization between Proton Drive and the file systems on your device and will support the app on desktop and notebook in the future. The link indicates the entry’s location by referencing the parent entry and by storing the name of the entry. a link - this identifies the entry’s position in the folder tree.a node - this keeps track of the entry’s metadata (for example, type, size, creation, and modification time) and its attributes.In the future, Proton Drive will allow administrators to create a volume for their organization and to offer access to members of the organization.Įach file and folder in Proton Drive is described by two entities: moving, renaming, and deleting files and foldersĪll content in Proton Drive lives inside a volume, an allotted amount of storage space, with each user having their own private volume.organizing their Proton Drive content into folder hierarchies.uploading, downloading, and previewing files.With this in mind, our goal is to ensure that the presence of encryption does not hinder the user in any way from seamlessly: modifying the file structure without your knowledge.adding new files and attributing them to you.viewing or changing the contents of your files.This model prevents any attacker who gains access to one of our servers from: Proton Drive’s design is based on end-to-end encryption. It offers secure online storage space for our users’ photos, documents, and other files with the same focus on privacy and security as the other Proton products. Proton Drive is the newest addition to the Proton encrypted ecosystem. Proton Drive (new window) has been released and is now available for everyone (new window). While somewhat technical, this document is meant to be accessible to a general audience and attempts to explain how Proton Drive works in plain language. This article documents Proton Drive’s security model by showing how it uses end-to-end encryption to protect your sensitive data. Last update on JanuPublished on August 31, 2020 ![]()
