Abstract:
The present invention relates to a method and system for 2-factor authentication for network connected storage devices based on the use of a second communication unit, such as a smart mobile phone.

Claim (Index 1):
A method for 2-factor authentication for access to an encrypted storage device in a computer system, the method comprising the steps, when initiating the computer system for encryption of the storage device, of:\n downloading from a network connected server an encryption control app, (ECA) to a smart mobile phone (SMP); activating the ECA; establishing, by the ECA, a short range communication connection to the computer system comprising an encryption module (CM); retrieving by the ECA from the computer, a unique ID, and then transferring the unique ID to the network connected server; receiving, by the SMP, an activation code from the network connected server, and the SMP transferring the activation code to the computer system; receiving a Master Password and a PIN code from a user at the SMP, and the ECA transferring the Master Password and the PIN code to the CM; generating, by the CM, a Key File comprising encryption keys to be used by the CM in encryption and decryption operations, and then encrypting the Key File using the Master Password as a first encryption key, and then encrypting the Master Password using the PIN code as a second encryption key; transferring the encrypted Key File to the SMP; storing the encrypted Key File within the SMP; deleting the Key File and the Master Password in the computer system; storing the encrypted Master Password in the computer system; and the method further comprising the steps of, when the computer system is attempted to be started up on subsequent occasions after the initiation of the computer system for encryption of the storage device:\n transferring the stored encrypted Key File from the SMP to the CM; \n receiving the PIN code at the SMP; \n transferring the PIN code from the SMP to the CM; \n decrypting, by the CM, the encrypted Master Password using the PIN code as the second encryption key; \n decrypting, by the CM, the Key File using the Master Password as the first encryption key; \n activating, by the CM, encryption and decryption modules with the encryption keys from the Key File; and \n deleting, by the computer system, the encrypted Key File and the unencrypted Master Password.
