Abstract

The invention relates to electronic keys. The invention relates more particularly to an electronic key for secure access to an electronic cylinder. The invention relates to an electronic key (1) enabling control of access to a mecatronic cylinder, wherein said key comprises at least one memory (3) for storing access information, and a microprocessor. The invention is characterized in that said key comprises at least one means of wireless communication with a server (7), comprising an access profile data base, wherein said access information can be remotely modified according to the access profile associated with said key.

Claims

1. An electronic key (1) enabling control over access to a mecatronic cylinder, wherein said key comprises at least one memory (3) for storing access information, and a microprocessor, characterized in that [said key] includes at least one antenna (6) and one means of wireless communication (5) with a server (7) containing a database of access profiles and in that said access information can be modified remotely according to the access profile associated with said key.

2. An electronic key according to claim 1, characterized in that said means of wireless communication includes a communications module.

3. An electronic key according to claim 1, characterized in that said means of wireless communication includes a global positioning module.

4. An electronic key according to claim 1, characterized in that said means of wireless communication includes both a communications module and a global positioning module.

5. An electronic key according to claim 2 or 4, characterized in that said communications module is a GSM, GPRS, or UMTS-type data communications module.

6. An electronic key according to claim 3 or 4, characterized in that said global positioning module is a satellite-based, GPS-type, global positioning module.

7. An electronic key according to claim 3 or 4, characterized in that said global positioning module is an Earth-based, GSM-type, global positioning module.

8. An access control system that includes an electronic key and a server containing a database of access profiles, wherein said electronic key contains at least one wireless communications module to communicate with said server and wherein said server contains a means to manage the access profiles associated with said key.

9. A process for communications within the system according to claim 8, characterized in that it includes at least one step for sending an access profile from said server to said electronic key.

10. A process according to claim 9, characterized in that it also includes a previous step in which the electronic key sends at least one element of information about its global positioning and in which said access profile includes at least one access permission associated with said global positioning information.

11. Process according to claim 10, characterized in that said access profile also includes a time parameter associated with said authorization, of which there is at least one [sic].

12. Process according to claim 9, characterized in that said access profile includes at least one element of information about global positioning, at least one timing information, and at least one access authorization associated with said global positioning information and said timing information, and in that said electronic key carries out a step to compare said global positioning information against its current global positioning and to compare said timing information against the current time in order to validate said authorization.
