A DDoS prevention scheme for session resumption SEA architecture in healthcare IoT

We propose a scheme for DDoS prevention in session resumption based end-to-end security for healthcare Internet of Things. In the proposed scheme a certificate based DTLS handshake takes place for mutual authentication between Smart e-Health Gateway and client. The end-to-end communication between client and medical sensors is susceptible to replay and DDoS attacks, and the communication is made secure by ensuring all requests to the medical sensor are sent through the Smart e-Health Gateways in the fog layer. This model not only makes the communication more secure, but also reduces the load on the resource-constrained medical sensors.
