“…Thus, this increases the probability of acquisition of an identical secret key between two legitimate users without going through the information reconciliation stage. Compared to other studies that also add a pre-processing stage [ 35 , 36 , 37 , 38 ], we can show that our proposed SKG scheme is simpler because it can reduce the information reconciliation stage. The advantage of losing this stage is the reduced difficulty of implementation because there is no exchange of parity bits.…”

“…Instead of directly changing the RSS measurement results into bits, we chose to add the pre-process stage using the MK method. Several studies [ 35 , 38 ] expose that the addition of the pre-processing method before the quantization will reduce the incompatibility of the resulting bits. Our proposed pre-process method i.e., modified Kalman is a combination of the polynomial regression and modified Kalman filter.…”

“…This method performs smoothing or fitting, so it increases reciprocity between the two users and reduces the incompatibility of the bits produced. Some studies in [ 35 , 36 , 37 , 38 , 39 ] show that the utilization of this method can reduce the mismatch of bits produced but still requires an information reconciliation stage to correct the mismatch bits. This condition results in the increasing computational time needed, because of the increasing number of stages that must be passed.…”

Limitations of the computational and energy capabilities of IoT devices provide new challenges in securing communication between devices. Physical layer security (PHYSEC) is one of the solutions that can be used to solve the communication security challenges. In this paper, we conducted an investigation on PHYSEC which utilizes channel reciprocity in generating a secret key, commonly known as secret key generation (SKG) schemes. Our research focused on the efforts to get a simple SKG scheme by eliminating the information reconciliation stage so as to reduce the high computational and communication cost. We exploited the pre-processing method by proposing a modified Kalman (MK) and performing a combination of the method with a multilevel quantization, i.e., combined multilevel quantization (CMQ). Our approach produces a simple SKG scheme for its significant increase in reciprocity so that an identical secret key between two legitimate users can be obtained without going through the information reconciliation stage.

Physical layer security protocols have recently been deployed in the context of Wireless communications. These are derived from the intrinsic characteristics of the communication media for key generation, sharing and randomness extraction. These protocols always seek to exhibit both low computational complexity and energy efficiency, whilst also maintain unconditionally secure communications. We present herein, a comprehensive literature review of existing "state-of-the-art" quantisation schemes for physical layer security, with a strong emphasis upon key performance metrics and intrinsic channel characteristics. Our survey seeks not only to concentrate upon the most common quantisation methods, hence their efficiency during key generation; but also crucially, describes the inherent trade-offs as between these standardised metrics. The exact way(s) in which these metrics are duly influenced by quantisation schemes is also discussed, by means of a comprehensive critical narrative of both existing and future developments in the field.

SummaryIn wireless body area networks (WBAN), device authentication and key agreement are the critical issues. In any real‐world cryptographic system, issues like these can be handled by one of the most practical bio‐cryptosystem schemes popularly known as fuzzy vault (FV). The secret key is encoded in a polynomial equation merged with physiological value and then combined with chaff (noise) points forming the FV. The most critical and computational intensive task in the FV is the chaff point generation, that is used to hide the valid point inside the vault pattern. In this paper, we propose an Enhanced Flower Pollination Algorithm based Chaff Point generation method with Hardware (EFPCH) implementation and have been proved to be a computationally fast and feasible algorithm for hardware implementation. The security of the FV depends on the infeasibility of the polynomial reconstruction and also in large number of chaff point. The existing methods for chaff point generation had taken less number of valid points and generate a maximum of 200 chaff points. But in our experimental result, we generated large number of chaff point (1:12) with a considerable amount of valid points over the existing algorithm. This work describes the key agreement model and implementation step required for identifying External programmer attached to the patient pacemaker. However, existing key agreement schemes have too many computational intensive tasks, making it unsuitable for system‐on‐chip (SoC) implementation. In the result of the described work, a practical SoC implementation of the wireless environment in WBAN is experimented. The results show that our proposed model has a more efficient implementation in generating larger chaff points and performs better than other current methods.
