Review on Communication Security Issues in IoT Medical Devices
10.2.1 Highlights on Secure Authentication Scheme over IoT Communication
Moosavi et al. (2014) developed a secure mutual authentication scheme for a radio frequency
identification (RFID) implant system. This system relies on elliptic curve cryptography
(ECC) and the D-Quark lightweight hash technique. Performance of this work is quite
desirable in order to implement resource-constrained medical devices. Raza et al. (2013)
evaluated the system to find out intrusion in IoT network called SVELTE. In order to evaluate SVELTE, Raza tested it with routing attacks such as spoofing, sinkhole, and selectiveforwarding. SVELTE was implemented in the Contiki OS. It detects attacks in simulated
scenarios. Nieminen et al. (2014) proposed an anonymous verification scheme, which can
defend some prominent properties, for example, sensor obscurity, cloning issue, and sensor untraceable. This work uncovered that the proposed authentication scheme will be
appropriate in numerous IoT applications where the protection of the sensor development
is assured. Qiu and Ma (2015) and Gope and Hwang (2015) proposed an enhanced authentication scheme for 6LoWPAN in machine-to-machine (M2M) communications. Rahman
and Shah (2016) concentrated on a basic part of IoT connected with internet protocols. In
IoT communication, constrained application protocols (CoAP) bind datagram transport
layer security (DTLS) as the security operator. In spite of this, there are some areas where
DTLS is as yet missing and can be considered a threat to the protocol.
The work carried out at present is focused only on the problem of secure authentication.
Past research in this field was focused on security attacks. In-depth, major challenges in
medical devices are protocol standardization and optimizing communication security of
medical devices. The standardization and optimization of IoT protocol are discussed in
the following sections.
10.2.2 Highlights on Standardization and Optimization of IoT Protocol
Sheng et al. (2013) conducted a survey on the Internet Engineering Task Force (IETF)
protocol suite with regard to the IoT. Considering each layer in the IETF protocol suite,
the author argued that the technical challenges such as constrained protocols in IoT and
research opportunities still have more scope. Sye Loong Keoh et al. (2014) elaborated
about the efforts in the IETF standardization IoT system. The author reviewed the communication security solutions for IoT, particularly security protocols, to be utilized as
part of the CoAP.
Al-kashoash et al. (2016) proposed a new routing metric in routing protocol (RPL) which
reduces the number of packet drops when congestion occurs. Additionally, Al-kashoash
proposed a new RPL objective function called congestion-aware objective function
(CA-OF). This function powerfully performs when congestion occurs by low congestion
route selection technique. Raza et al. (2012) proposed 6LoWPAN header compression for
DTLS. This compression technique considerably decreases the amount of extra security
bits. Based on the review, the protocol constraints such as header compression, buffer overflow, routing selection, congestion, less throughput, lost packets, energy consumption, and
packet delivery issues are identified.
10.2.2.1 Standards
Standards are essential certification for IoT medical devices and communication protocols.
Many standards associated with medical devices are discussed in Table 10.1. Standards
provide concrete support to the good security of the medical devices.
