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.
