Method and Apparatus for Managing Encrypted Folders in Network System

摘要

A method for managing an encrypted folder in a shared storage in a network system, the method comprising generating a symmetric cryptographic key for a folder; generating a first metadata according to a symmetric encrypting function of the symmetric cryptographic key for the folder operating with a symmetric cryptographic key for a remote folder; and creating the folder with the first metadata in the remote folder; wherein the remote folder has a second metadata or an access control list comprising at least one entry with at least one identity of at least one collaborator, at least one public key of the at least one collaborator and at least one encryption of the symmetric cryptographic key for the remote folder according to an asymmetric encrypting function operating with the at least one public key of the at least one collaborator, for providing the symmetric cryptographic key for the remote folder.
