“…Many key generation and agreement schemes have been developed in recent years, such as PSKA [6], OPFKA [7], ELPA [8] and Multi-Biometric and Physiological Signal-Based Key Agreement (MBPSKA) [12]. Each of these schemes provides the participating devices with the capability to derive a symmetric key from the shared physiological signal (i.e., ECG in this context).…”

“…ELPA [8] is a key generation and agreement scheme that, unlike the above works, does not use the fuzzy vault primitive and instead uses Linear Prediction Coding (LPC). ELPA allows two BAN devices measuring ECG from the same person to agree upon the same symmetric key.…”

“…To secure BAN against potential attacks, several techniques are proposed to facilitate security keys distribution between BANs sensors using Electrocardiogram (ECG) signals, such as the fuzzy commitment and the fuzzy vault approaches, where each of them presents unique performance limitations and design trade offs [5]. Physiological Signal Based Key Agreement (PSKA), Ordered Physiological Feature-based Key Agreement (OPFKA) and ECG Linear Prediction key Agreement (ELPA) [6]- [8] are examples of key generation and agreement schemes that exploit the unique capability of accessing physiological signals. Specifically, these schemes use ECG to derive a symmetric key to secure all future communications between compatible sensors.…”

A New Attack Method Against ECG-Based Key Generation and Agreement Schemes in Body Area Networks

Body Area Networks (BAN) are wireless networks designed for deployment on or within the human body. These networks are primarily intended for application within the medical domain due to their capabilities for enabling wireless monitoring of physiological signals, and remote administration of medical devices. Due to their intended use case, securing these devices is paramount. In recent years, several key generation and agreement schemes that rely upon physiological signals of the wearer are developed. However, we have found that the application of Electrocardiogram (ECG) signals in this context may not be appropriate due to a potential vulnerability, wherein previously recorded ECG signals could be used against current and future key agreement attempts to compromise their security. This is a violation of temporal variance which is one of a few properties that make ECG signals suitable for use in key agreement schemes. By extracting the QRS complex from prior recordings and distributing them apart from one another we can construct synthetic signals that have a high level of coherence, and thus allow for the key to be intercepted. Based on the conducted experiments we have found that the proposed attack method yields a 0.7 coherence level regardless of how far away the adversary is from the target. This makes the success of such an attack extremely likely and is therefore a real threat to the security of these schemes.

Objective: To review different key agreement schemes which are used to establish Wireless body area network (WBAN) on the basis of identified attacks and also evaluate the schemes on performance parameters. Method: In this paper, an overview of WBAN, its architecture, difference between WSN and WBAN, IEEE 802.15.6 specifications of WBAN, attacks in the environment and security essentials are discussed at first. It further divides the key agreement schemes into four classes and provides an extensive review of the schemes on the basis of distinct parameters viz.

“…Key distribution has been proposed in many active research works based on dynamic biometric features [12], [13] and radio channel features [14]- [16]. In [12] and [13], the key generation schemes were proposed by using Electrocardiograph (ECG). Due to the reciprocity, space uniqueness and time variability of wireless channel, a secure key can be obtained by measuring the channel gains [17].…”

Device-to-Device (D2D) communication is a promising method for the emerging Internet of Things. Secure information exchange plays a key role in the application of D2D communication. Considering that the wireless devices are powered by batteries, in this paper, a lightweight secure D2D system is designed by using multiple sensors on mobile devices. Specifically, by leveraging an acceleration sensor equipped in two wireless devices, a lightweight and efficient key distribution scheme for secure D2D communication is proposed. Based on the distributed secure key, an efficient near-field authentication is developed with a speaker and a microphone to determine whether these two devices are physically close; and a secure information exchange scheme with high efficiency, which includes message encryption/decryption and message authentication, is presented over the audio channel and the RF channel. The Extensive experiments are provided to demonstrate that our system can achieve a secure information exchange between two wireless devices with low energy consumption and computing resources.INDEX TERMS Secure D2D communication, sensors, key distribution, near field authentication, Internet of Things.
