Abstract:
1. A method for managing information in a large capacity universal integrated circuit card, the method comprising: securely storing a mass storage file in a mass storage file system of a large capacity universal integrated circuit card by encrypting a content of the mass storage file using a key determined by a mass storage secure controller of the large capacity universal integrated circuit card, the mass storage file comprising the content; associating the mass storage file stored in the mass storage file system with an ISO directory file of an ISO file system of the large capacity universal integrated circuit card, wherein the ISO directory file in the ISO file system is associated with a security configuration defining security requirements for accessing the ISO directory file of the ISO file system, further wherein the ISO directory file is a directory file according to ISO 7816, further wherein the associating of the mass storage file stored in the mass storage file system with the ISO directory file of the ISO file system is performed by the mass storage secure controller located in the large capacity universal integrated circuit card; securing the content of the mass storage file stored in the mass storage file system in order to make the content inaccessible; revealing the content of the mass storage file if the security requirements of the ISO directory file in the ISO file system are met; requesting access from the mass storage file system to the content of the mass storage file stored in the mass storage file system; determining if the content is securely stored; in response to determining that the content is securely stored, delivering security requirements to the ISO file system and determining whether the delivered security requirements meet the security requirements defined by the security configuration associated with the ISO directory file of the ISO file system which is associated with the mass storage file stored in the mass storage file system; in response to determining that the security requirements are met, revealing the content of the mass storage file stored in the mass storage file system.
