Problems solved by technology

[0008] Using this method to provide a smart card for providing multiple encryption functions is too expensive and complicated, because it requires the smart card to generate and maintain many different keys, each key is used for a specific purpose
[0009] It is an object of the present invention to provide a smart card which can be used to provide multiple encrypted services and which is less expensive and complex than the previously proposed solutions

[0098] best practice

[0099] FIG. 2 depicts members A and B of an organizational structure including a financial department 22 , a legal department 23 and a security department 24 . Members of the organization have their own smart cards, and the smart cards of members A and B are denoted as 10A and 10B respectively in FIG. 2 . Members A and B also have respective computers 20A and 20B, each of which includes a smart card interface that enables the smart card to be operatively coupled to the computer.

[0100] The various departments of the organization are interconnected via the network 25 . The computers 20A and 20B are also connected to the network 25 , and the printer 21 is also connected to the network 25 . The printer 21 has a smart card interface through which a smart card can be coupled to the printer.

[0101] The form of the member's smart card will now be described with reference to member A's smart card 10A, the other smart cards being essentially the same. The s...

Abstract

A processor-based system may use a volatile memory with a shadow phase change memory. The shadow phase change memory may be directly coupled to the controller. The controller may also be coupled to the volatile memory which, in turn, may, in some embodiments, be directly coupled to the phase change memory. In a standby mode, the volatile memory may be powered down. In some embodiments, faster speeds may be achieved with lower power consumption and less risk of data loss in the case of a crash or other system failure.

Description

technical field [0001] The present invention relates to a smart card with encryption function and a method and system for providing encryption services in organizations using the smart card. [0002] The term "organization" as used herein is intended to cover any formal or informal group, such as a business enterprise, interest group, international organization or nation. Furthermore, the term "smart card" as used herein is intended to include any small-sized object (such as a credit card-sized object) incorporating processing functionality, usually on a microcontroller, using physical contact devices or devices such as inductive, capacitive, photoelectric or Similar non-contact means the object of small size is externally accessible through any suitable interface. The processing functions may be based on a program-controlled processor or dedicated circuitry. The smart card may be powered in any suitable manner such as by an external power source via physical contact, by on-...
