Abstract
A method for decoupling user authentication and data encryption on mobile devices includes generating an encryption key ('EK') for encrypting data and a key encryption key ('KEK') for encrypting the EK, obtaining an encrypted EK by encrypting the EK using the KEK, storing the encrypted EK on a data container device (“DCD”), and storing the KEK on a key vault device (“KVD”) that is distinct from the DCD. Neither the EK nor KEK are generated using a user authentication secret as a seed. The DCD may fetch the KEK from the KVD as desired to decrypt the EK and to encrypt and decrypt data stored on the DCD. Examples of the DCD include a memory stick, smartphone, or tablet computer, while examples of the KVD include a dongle, smartphone, or tablet computer.
