“…Moreover, the overhead of Per-IO-Prng is at 6.27%; notably, only 0.77% (6.27–5.50%) is added with the application of the PRNG function to more randomly change the keys and improve security. A similar experiment was provided in our previous work [ 8 ].…”

“…By contrast, a one-time password (OTP) [ 7 ] is a system in which a password is valid for only one login session on a computer or for a single data transfer over a network. Therefore, to avoid the shortcomings associated with static key authentication, we applied OTP with CoAP in our previous work [ 8 ]. Another technique, one-time pad [ 9 ], refers to a key that can only be used once (i.e., nonrepeating) for encrypted operations.…”

The ecosystem for an Internet of Things (IoT) generally comprises endpoint clients, network devices, and cloud servers. Thus, data transfers within the network present multiple security concerns. The recent boom in IoT applications has accelerated the need for a network infrastructure that provides timely and safe information exchange services. A shortcoming of many existing networks is the use of static key authentication. To enable the use of automatic key update mechanisms in IoT devices and enhance security in lightweight machine-to-machine (M2M) communications, we propose a key update mechanism, namely, double OTP (D-OTP), which combines both one-time password (OTP) and one-time pad to achieve an IoT ecosystem with theoretically unbreakable security. The proposed D-OTP was implemented into the Constrained Application Protocol (CoAP) through the commonly used libcoap library. The experimental results revealed that an additional 8.93% latency overhead was required to obtain an unbreakable guarantee of data transfers in 100 CoAP communication sessions.

“…Finally, we noticed from the abovementioned key generation techniques that they can be implemented either hardware such as being presented in articles [13,14,19] or standard common software schemes such as CoAP, CRT, DCT, MEMK, and pseudorandom number generator which are realised in articles [10,12,13,[16][17][18]. According to the system configuration, designers can choose the suitable method for key generation.…”

The internet of things (IoT) has provided a promising opportunity to build powerful systems and applications. Security is the main concern in IoT applications due to the privacy of exchanged data using limited resources of IoT devices (sensors/actuators). In this paper, we present a classification of IoT modes of operation based on the distribution of IoT devices, connectivity to the internet, and the typical field of application. It has been found that the majority of IoT services can be classified into one of four IoT modes: gateway, device to device, collaborative, and centralized. The management of either public or symmetric keys is essential for providing security. In the present paper, we survey different key management protocols concerning IoT, which we further allocate in a map table. The map table is a link between modes of operation and the associated security key management elements. The main target of this mapping table is to help designers select the optimum security technique that provides the best balance between the required security level and IoT system mode constraints.
