Abstract
This disclosure describes techniques for updating firmware of a secure element. The techniques include operations comprising: receiving, by a gateway device, from a remote source, a firmware file; receiving, by a processing element implemented on the gateway device, ephemeral session specific key material for a first secure element implemented on the gateway device; dividing the firmware file into a plurality of data chunks; applying, by the processing element, the ephemeral session specific key material to a first data chunk of the plurality of data chunks to generate a first data packet; and sending, by the processing element, the first data packet to the first secure element.
