Problems solved by technology

[0005] While ME itself can be considered to provide an appropriate degree of security, such levels of security tend to be specific to ME manufacturers, and the storage capacity is considered insufficient for all types of user data (specifically, multimedia data )

Embodiment Construction

[0058] As can be appreciated from the foregoing description, and in light of the more detailed description of certain embodiments below, the present invention advantageously addresses limitations that exist on current circuit cards, such as those associated with providing data protection simply based on PIN codes. Mechanism-related constraints. As mentioned above, they are mainly related to applications (e.g. GSM / USIM) and their associated data (e.g. IMSI or PLMN lists, etc.), and where data is not directly linked to any such application (e.g. user private files, , videos, personal messages) fall within the same security zone.

[0059] The present invention defines a data protection mechanism that can be used together with existing PIN protection, if desired, to provide a higher level of security for all types of data stored on circuit cards.

[0060] Moreover, data storage in circuit cards is currently based on elementary files (Elementary Files), and these elementary files ...

Abstract

The present invention provides for a method data of achieving protection in a circuit card such as a UICC arranged for storage of a plurality of data elements and providing protection on the basis of a domain protection-element serving to define operations that can be permitted on a data element, and on the basis of a password protection-element serving to control access to a data element and wherein at least one of the plurality of data elements is associated with both a domain protection-element and a password-protection element, and the invention further provides for a circuit card arranged for the secure storage of such data elements and for a ME arranged to employ such a circuit card.

Description

technical field [0001] The present invention relates to circuit cards and, in particular, to arrangements and methods for protecting data stored on circuit cards. Background technique [0002] Handheld devices such as cellular telephone handsets and other forms of mobile equipment (ME) have become popular devices / interfaces for storing and preserving large amounts of (personal) data as their functionality has increased. [0003] Such data may include, for example, private photos, videos and SMS messages, and the user may generally choose to store such data within the ME, or in relevant parts of a Universal Integrated Circuit Card (UICC) such as a Subscriber Identity Module (SIM) card, Or even in the storage area on the network side provided by the network operator, or on other media devices such as memory cards. [0004] Considering the volume and possibly private / sensitive nature of the data to be stored, the storage area should provide sufficient storage capacity, appropr...
