Definitions

• Levels 2 and 3 are generally referred to as "software” below.
• each version of the software is broken down into several subparts, including:
• a boot loader is a software program for launching one or more operating systems (known as "multi-boot”), that is, it allows use different systems at different times on the same machine.
• the update and partition scheme supports the maintenance of all or part of the user settings and / or other partitions of interest, between updates, with or without update of format and without compromising the ability to roll back.
• step 250 we display the logo and go to step 255 during which it is determined if all the sub-parts of the proprietary software have have been treated. If no, return to step 210. If yes, in step 260, it is determined whether all required subparts have been found. For example, for a Linux-based system, this is at least one kernel subpart and a subpart with the root file system. If you are in a secure mode, the kernel must be encrypted and the root file system must be signed.
• step 305 the previous standard proprietary software and restoration software are searched in the partition card. Then, during a step 310, it is determined if more software has been found in step 305. If no, go to step 320. If yes, in a step 315 , we display the list of found software and we ask the user to choose one. Once this choice is made by the user, we go to step 320, during which it is determined whether to perform a re-authoring of the software, according to the value of the associated flag. If no, we go to a step 330. If yes, during a step 325, we proceed to re-authoring and re-writes the proprietary software and we erase the associated flag. Then, we go to step 330 during which we load the proprietary software.
• sub-type which may take, in the case of a "proprietary software” type, the "standard”, “maintenance”, “development” and “reserved” values,
• the bootloader implementation can support either static mode only, for maximum security, or both static and dynamic mode, or only dynamic mode, as discussed below.
• the bootloader is preferably encrypted or signed.
• FIG. 14 shows an example of partition configurations in dynamic switching mode from the back-to-front and maintenance-only mode after, before and after the update.
• the partition configuration Prior to the update, the partition configuration includes the bootloader partition 1405, the partition card partition 1410, the software partition A, active, 1415, and the reusable software partition B, 1420.
• the partition configuration includes the bootloader partition 1405, the modified partition card partition 1430, the active and modified software partition C, 1435, and the modified maintenance software partition D 1445.
• the server If no software update is available, the server returns the "204 No Content” response. If an updated version is available, the server returns the answer "200 OK" and, in the body of the response, a description of the update (version, size and new features). This can be done using a form of free text, an XML form (acronym for "extensible markup language” for extensible markup language) or an ".ini” syntax, depending on the tool available to use this response. One can also specify a language in the request, using a header "Accept-Language", so that the server returns a description in this language.
• the server finds the appropriate version that is likely to update the current version, which may not be the latest version, as discussed below. This procedure also helps in case the update pays off. In such a case, the server returns information indicating that the updated software can only be downloaded after payment. The user can contact the seller to make this payment.
• a local update method such as USB (Universal Serial Bus), as explained below, can be used for the update.
• USB Universal Serial Bus
• version verification for local update, for example from USB / MMC-SD (acronym for "USB / multimedia card - Secure Digital" for secure digital multimedia USB card ). This is useful in the case of a downgrading, for example for a demonstration or an evaluation version.
