Andrei Gurtov, Tatiana Polishchuk, Max Wernberg
The increased utilization of the new types of cockpit communications, including controller⁻pilot data link communications (CPDLC), puts the airplane at higher risk of hacking or interference than ever before. We review the technological characteristics and properties of the CPDLC and construct the corresponding threat model. Based on the limitations imposed by the system parameters, we propose several solutions for the improved security of the data messaging communication used in air traffic management (ATM)...

Vehicle ad hoc networks (VANETs) is a promising network scenario for greatly improving traffic efficiency and safety, in which smart vehicles can communicate with other vehicles or roadside units. For the availability of VANETs, it is very important to deal with the security and privacy problems for VANETs. In this paper, based on certificateless cryptography and elliptic curve cryptography, we present a certificateless signature with message recovery (CLS-MR), which we believe are of independent interest. Then, a practical certificateless conditional privacy preserving authentication (PCPA) scheme is proposed by incorporating the proposed CLS-MR scheme...

Electronic patient portals are increasingly utilized in contemporary health care systems. Patient portal use has been found to be beneficial in multiple specialties, particularly in management of chronic diseases. However, there are disparities within portal use. For example, individuals who are racial and ethnic minorities and persons from lower socioeconomic status are less likely to enroll and use patient portals than non-Hispanic white persons and persons with higher socioeconomic status. Because portal use and, specifically, patient-provider secure messaging has been associated with favorable health outcomes, disparities in use of these portals could affect health outcomes...

The Internet of Things (IoT) introduces many new challenges which cannot be solved using traditional cloud and host computing models. A new architecture known as fog computing is emerging to address these technological and security gaps. Traditional security paradigms focused on providing perimeter-based protections and client/server point to point protocols (e.g., Transport Layer Security (TLS)) are no longer the best choices for addressing new security challenges in fog computing end devices, where energy and computational resources are limited...

INTRODUCTION: The prevalence of chronic pain is enormous. In America, the management of chronic pain and opioids remains a critical focus. Guidelines recommend pain agreements as part of the management of chronic pain and opioids; however, evidence of improvement in patient outcomes is lacking. An aspect of patient outcome includes utilization of healthcare resources, such as emergency department visits and hospitalizations. It remains uncertain whether the use of pain agreements lessens healthcare utilization...

BACKGROUND: Cognitive behavioral therapy is an efficacious treatment for child anxiety disorders. Although efficacious, many children (40%-50%) do not show a significant reduction in symptoms or full recovery from primary anxiety diagnoses. One possibility is that they are unwilling to learn and practice cognitive behavioral therapy skills beyond therapy sessions. This can occur for a variety of reasons, including a lack of motivation, forgetfulness, and a lack of cognitive behavioral therapy skills understanding...

Introduction: Use of electronic secure messaging (SM) is rapidly growing in various healthcare settings. However, there is a large number of patients that choose not use SM or use it minimally. Thus, understanding preferences for patient-provider communication modalities is critically important, particularly among military healthcare beneficiaries. The purpose of this study was to assess preferences for patient-provider communication modalities (in person, telephone, SM, or mail) among a sample of patients, providers, and staff located at five Air Force military treatment facilities across the USA...

BACKGROUND AND OBJECTIVE: Advances in information and communication technologies boost the sharing and remote access to medical images. Along with this evolution, needs in terms of data security are also increased. Watermarking can contribute to better protect images by dissimulating into their pixels some security attributes (e.g., digital signature, user identifier). But, to take full advantage of this technology in healthcare, one key problem to address is to ensure that the image distortion induced by the watermarking process does not endanger the image diagnosis value...

Wireless body area network (WBAN) provides a medium through which physiological information could be harvested and transmitted to application provider (AP) in real time. Integrating WBAN in a heterogeneous Internet of Things (IoT) ecosystem would enable an AP to monitor patients from anywhere and at anytime. However, the IoT roadmap of interconnected 'Things' is still faced with many challenges. One of the challenges in healthcare is security and privacy of streamed medical data from heterogeneously networked devices...

At present, the standardisation of electrical equipment communications is on the rise. In particular, manufacturers are releasing equipment for the smart grid endowed with communication protocols such as DNP3, IEC 61850, and MODBUS. However, there are legacy equipment operating in the electricity distribution network that cannot communicate using any of these protocols. Thus, we propose an infrastructure to allow the integration of legacy electrical equipment to smart grids by using wireless sensor networks (WSNs)...

Inspired by the information theory, a new concept of re-programmable encrypted graphene-based coding metasurfaces was investigated at terahertz frequencies. A channel-coding function was proposed to convolutionally record an arbitrary information message onto unrecognizable but recoverable parity beams generated by a phase-encrypted coding metasurface. A single graphene-based reflective cell with dual-mode biasing voltages was designed to act as "0" and "1" meta-atoms, providing broadband opposite reflection phases...
