Abstract
An apparatus in one embodiment comprises a processing platform configured to communicate over a network with a plurality of Internet of Things (IoT) devices. The processing platform receives at least a first intermediate message from a first gateway of the network, receives one or more additional intermediate messages from each of one or more additional gateways of the network, associates the first and additional intermediate messages with one another based at least in part on a common message identifier detected in each such intermediate message, and processes the associated first and additional intermediate messages to recover a device message from a given one of the IoT devices. The first intermediate message is based at least in part on at least one application of a designated cryptographic function to the device message utilizing a corresponding key. At least one of the one or more additional intermediate messages provides at least a portion of the key.
