Embodiment Construction

[0031] First, referring to the access control device according to the present invention figure 1 .

[0032] The access control device DEV includes a certain number of multifunctional ports U 1 , U 2 , U 3 ,...,U i , and allow the connection of peripheral P.

[0033] Single Multifunction Port U 1 Can be used in a device DEV, but the invention is more particularly advantageous for using multiple multifunction ports, as explained below.

[0034] The term "multifunction port" here refers to any general-purpose port that allows the connection of peripherals belonging to different peripheral categories, as opposed to a "single-function port" dedicated to one type of peripheral, such as a PS / 2 port (use limited to connection of user peripherals of the mouse or keyboard type), IEEE1394 port or Ethernet port (use limited to connection of network equipment), VGA port (use limited to connection of monitor), etc.

[0035] By way of example, a USB port may be mentioned here as a mul...

Abstract

The invention relates to a device suitable for controlling access to a computer system, the device includes at least one multifunctional port (Uj) capable of connecting various peripheral devices and an access interface (INT) capable of connecting a computer system, the device is characterized in that , also includes an access management component (Macc) connected between the multifunction port (Uj) and the interface (INT), the access management component is physically configured as a peripheral device (P) connected to the multifunction port (Uj) ) to authorize access to an interface as long as said peripheral belongs to a specific and permanently associated peripheral class to the connected multifunction port (Uj). The invention also relates to a corresponding access control method.

Description

technical field [0001] The present invention relates to the field of secure access to computer systems and in particular to the field of controlled access to computer systems by means of specific peripherals. Background technique [0002] Existing computer systems have a certain number of ports that allow the connection of different kinds of peripherals that can serve as user interfaces, connections to other computer systems, and data storage. [0003] Thus, the integrity of these computer systems can be compromised by physically connecting the ports of these systems to certain peripherals that contain malicious data, even without the user's knowledge. [0004] This is especially the case with USB (Universal Serial Bus) peripherals. USB ports are general-purpose ports of the "multifunction" type, i.e. they can accept a large number of different types of peripherals, for example, network interfaces, storage elements of the USB key type, keyboards, mice, webcams, etc. [000...
