“…Also not in the field of security, but interesting to mention is the work in [28] which presents a near-field-sensing transceiver for intra-body communication between two or more devices as well as individuals themselves. The proposed transceiver features an electric-field sensor suitable for the fields generated by the human body when subjected to an electric signal.…”

Abstract-Device pairing is the problem of having two devices securely establish a key that can be used to secure subsequent communication. The problem arises every time two devices that do not already share a secret need to bootstrap a secure communication channel. Many solutions exist, all suited to different situations, and all with their own strengths and weaknesses.In this paper, we propose a novel approach to device pairing that applies whenever a user wants to pair two devises that can be physically touched at the same time. The pairing process is easy to perform, even for novice users. A central problem for a device (Alice) running a device pairing protocol, is determining whether the other party (Bob) is in fact the device that we are supposed to establish a key with. Our scheme is based on the idea that two devices can perform device pairing, if they are physically held by the same person (at the same time). In order to pair two devices, a person touches a conductive surface on each device. While the person is in contact with both devices, the human body acts as a transmission medium for intra-body communication and the two devices can communicate through the body. This body channel is used as part of a pairing protocol which allows the devices to agree on a mutual secret and, at the same time, extract physical features to verify that they are being held by the same person. We prove that our device pairing protocol is secure in our threat model and we build a proof of concept set-up and conduct experiments with 15 people to verify the idea in practice.

“…A data rate of 9.6 kbps was obtained by using FSK modulation with carrier frequency of 10.7 MHz [32,40]. The new component electrooptic sensor was introduced in the transceiver by Shinagawa et al [80]; a data rate of 10 Mbps was reached. The comparison of modulation schemes FSK and BPSK was conducted by Wegmueller et al [43].…”

Human body communication (HBC), which uses the human body tissue as the transmission medium to transmit health informatics, serves as a promising physical layer solution for the body area network (BAN). The human centric nature of HBC offers an innovative method to transfer the healthcare data, whose transmission requires low interference and reliable data link. Therefore, the deployment of HBC system obtaining good communication performance is required. In this regard, a tutorial review on the important issues related to HBC data transmission such as signal propagation model, channel characteristics, communication performance, and experimental considerations is conducted. In this work, the development of HBC and its first attempts are firstly reviewed. Then a survey on the signal propagation models is introduced. Based on these models, the channel characteristics are summarized; the communication performance and selection of transmission parameters are also investigated. Moreover, the experimental issues, such as electrodes and grounding strategies, are also discussed. Finally, the recommended future studies are provided.

“…The concept is to use a human body as communication channel between mobile device terminals. The concept of Personal Area Networks (PAN) [2] Near field IBC is demonstrated how mobile devices near the human body can exchange digital information by capacitive coupling in Pico ampere currents through the human body. In the year 2013 MirHojjat Seyedi [3] et al done a survey to examine the ongoing research in the area of Intra-body communication for body area network applications and gives IBC fundamentals, IBC mathematical models of the human body, IBC transceiver designs.…”

“…The prototype of the PAN transmitter operates at 330 kHz, 30V, with a transmission power consumption of 1.5mW for charging the electrode capacitance. Direct coupling by Masaaki Fukumoto [2] et al is a modified version of the basic capacitive method. The system operates by analog frequency modulation at frequencies within 50 kHz to 90 kHz for transmitting a simple protocol of ID numbers.…”
