Provisioning Capabilities
The SPA9x2 provides for secure provisioning and remote upgrade. Provisioning is achieved
through configuration profiles transferred to the device via TFTP, HTTP, or HTTPS.
The SPA9x2 can be configured to automatically resync its internal configuration state to a
remote profile periodically and on power up. The automatic resyncs are controlled by
configuring the desired profile URL into the device.
The SPA9x2 accepts profiles in XML format, or alternatively in a proprietary binary format,
which is generated by a profile compiler tool, SIP Profile Compiler (SPC), available from Linksys.
The SPA9x2 supports up to 256-bit symmetric key encryption of profiles. For the initial transfer
of the profile encryption key (initial provisioning stage), the SPA9x2 can receive a profile from
an encrypted channel (HTTPS with client authentication), or it can resync to a binary profile
generated by the Linksys SIP profile compiler. In the latter case, the SIP profile compiler can
encrypt the profile specifically for the target SPA9x2, without requiring an explicit key
exchange.
