To secure e-health communications, key management protocols play a vital role in the security process. Nevertheless, current e-health systems are unable to run existing standardised key management protocols due to their limited energy power and computational capabilities. In this paper, we introduce two solutions to tailor MIKEY-Ticket protocol to a such constrained environment. Firstly, we propose a new header compression scheme to reduce the size of MIKEY's header from 12 Bytes to 3 Bytes in the best compression case. Secondly, we present a new exchange mode to reduce the number of exchanged messages from 6 to 4. We use a formal validation tool to evaluate and validate the security properties of our tailored MIKEY-Ticket protocol. In addition, we evaluate both communication and computational costs to demonstrate the energy gain. The results show a decrease in MIKEY-Ticket overhead and a considerable energy gain without compromising its security properties.
