摘要:
A digital memory such as a memory card for mobile communication equipment, is adapted to be accessed by a plurality of users and have protected data stored therein. The memory is dynamically partitionable in private memory areas for storing data therein and has associated therewith a secrecy tool for securely allocating to the users respective private areas and permitting the users to access the respective private areas via a secure session channel to perform read/write commands in the respective private areas. Typically, the memory/card includes: a card interface controller for managing a physical communication layer between the digital memory and external host equipment, an internal memory having associated therewith a hardware lock to control access to the internal memory, a set of cryptographic modules to manage the secure session channel between the users and the digital memory, and a memory certificate for certifying a public key associated with the digital memory.

Users of mobile terminals in a communication network are provided controlled access to files in a file system through the steps of configuring the files as a file body containing a file content and a file header containing content profile information; providing a security identity module and a secure agent; storing in the security identity module user profile information identifying a set of content profiles allowed for access to the file system; extracting, via the secure agent, the content profile information from the headers of the files; retrieving, via the secure agent, the user profile information stored in the security identity module; checking the user profile information and the content profile information; and providing the user with access to those files in the file system for which the user profile information and the content profile information are found to match.
