DTLS handshake overhead prohibitive for battery-powered IoT

8/10 High

DTLS requires multiple data exchanges to negotiate channels and maintains state until closure, preventing sleep mode in battery-driven IoT devices. Energy and bandwidth overhead makes DTLS impractical for constrained devices.

TLS/DTLS requires two or more exchanges of data to negotiate the communication channel, a resource and energy extensive task. Also, both ends have to maintain the state of the channel until it is closed, stopping devices from entering sleep-mode.
