| <p>SEMS Lite agent gets an <em>update package</em> from the <em>update manager</em>. The upgrade package contains package meta data header and set of APDUs(MulticastCommands) to be sent to the SE for update. It may optionally also contain host control commands (e.g. Reset the secure element).</p> |
| <p>Format of the <em>update package</em>:</p> |
| <img alt="../../_images/Package.jpg" src="../../_images/Package.jpg" /> |
| <p>NXP provides customer package meta data and Multicast commands in JSON file. NXP also provides generator tool to turn the JSON file to binary file and .c/.h files. Customer can decide which one to be used by <em>update manager</em> according to their platform. <em>Update manager</em> should create <em>update package</em> from these files. This chapter has provided examples for the use of generator. It also provides links to the demos which will use the generated files to create <em>update package</em>.</p> |
| <div class="section" id="package-meta-data"> |
| <h2><span class="section-number">7.2.1. </span>Package Meta Data<a class="headerlink" href="#package-meta-data" title="Permalink to this headline">¶</a></h2> |
| <p>Package meta data includes information such as version and memory requirement. These information will help SEMS Lite agent to preprocess package before loading APDU commands to SE.</p> |
| <ul class="simple"> |
| <li><p>MulticastPackageFormatVersion: Version information of this json Format for MulticastPackages.</p></li> |
| <li><p>TargetEntityID: Entity ID, 16bytes long Binary Coded Decimal, of the target device where this MulticastPackage is intended to be executed on. It is an identifier of the key-set of the Multicast Applet Loader.</p></li> |
| <li><p>Target12nc: Target 12nc is a 12 digit numerical code identifying the target device where this MulticastPackage is intended to be executed on, as known to customers and used on EdgeLock2Go to identify device types.</p></li> |
| <li><p>requiredFreeBytesNonVolatileMemory: Minimum required free Non Volatile memory in bytes that have to be available on the target device before execution of this MulticastPackage.</p></li> |
| <li><p>requiredFreeBytesTransientMemory: Minimum required free transient (RAM) memory in bytes that have to be available on the target device before execution of this MulticastPackage.</p></li> |
| <li><p>MulticastPackageName: Giving a descriptive name to the complete Multicast Package.</p></li> |
| <li><p>MulticastPackageVersion: Version information of this MulticastPackage, describing the sum version over all contained content.</p></li> |
| <li><p>SubComponentMetaData: A list of subcomponents of this MulticastPackage, designating all Executable Load Files (ELFs) Contained. It usually contains one entry, but can have multiple in the case multiple dependent ELFs get modified. This list can be empty, e.g. for a KeyRotation or deletion of content.</p></li> |
| <li><p>SubComponentMetaData name: A human readable name for this subcomponent.</p></li> |
| <li><p>SubComponentMetaData aid: The Application Identifier (AID) of the Executable Load File (ELF) which makes up the content of this subcomponent. This is stored as string to have it formatted in upper-case hexadecimal and therefore recognizable form.</p></li> |
| <li><p>SubComponentMetaData version: Version information of this subcomponent.</p></li> |
| <li><p>SubComponentMetaData minimumPreviousVersion: Minimum version number of this subcomponent as installed on the secure element before this script is executed. If this field is omitted there is no minimum version requirement, e.g. initial Installation of an applet.</p></li> |
| <li><p>SignatureOverCommands: The signature over the multicast commands in an machine readable form. So it does not have to be parsed form the script commands. String encoding (upper-case hexadecimal) is chosen here, as many json parsers can not handle such large integer values.</p></li> |
| <li><p>MulticastCommands: The complete Multicast Applet Loader Script (certificate, signature, encrypted and signed commands) in ls-cgt format, encoded in base64.</p></li> |

| <p>NXP provides both SEMS Lite generate tool and JSON format in semslite\tools folder. Generate tool should only work with the JSON schema in the same release. For example, in SEMS Lite 2.0.0 (Refer to semslite\version_info.txt) the JSON package format version is 1.2. Generate tool should only use this JSON schema.</p> |
