ABSTRACT:
A method for generating a secure storage file system, including encrypting data using a symmetric key to obtain encrypted data, encrypting the symmetric key using a public key to obtain an encrypted symmetric key, storing the encrypted data and the encrypted symmetric key if the public key is associated with a user who only has read permission, generating an encrypted hashed data if the public key is associated with a user who has write permission, and storing the encrypted data, the encrypted symmetric key, and the encrypted hash data if the public key is associated with the user who has write permission.
