Generating random binary sequences is a fundamental requirement in cryptography. A binary sequence (BS) is a sequence of N bits and each bit has a value of 0 or 1. For securing sensors within Wireless Body Area Networks (WBANs), electrocardiogram (ECG) based BS generation methods have been widely investigated in which Inter-pulse Intervals (IPIs) from each heartbeat cycle are processed to produce BSes. Using these IPI-based methods to generate a 128-bit BS in real-time normally takes around half a minute.

In this paper, we propose MinDroid, a user-centric preventive policy enforcement system against SMS malware in Android devices. The design of MinDroid takes into consideration the user’s little understanding of the Android permission system. This can be done by deriving the policy rules from the behavioral model of the malicious SMS applications rather than adopting user-defined rules. MinDroid requires user intervention only during the first T time units from the application installation time.

Vehicular communications are emerging as a promising technology to enable communications using vehicles as network nodes. VDTNs appear as a novel approach to enable services and applications where it is not possible to define an end-to-end path. To allow communications in such challenging environments, VDTNs rely for their operation on cooperation between network nodes, which contributes to increasing network connectivity and improving overall network performance.

The wide dissemination of Internet around the world changed the way people communicate among them. The evolution of the information and communication technologies (ICT) or artificial intelligence (AI) allowed the creation of new types of services involving electronic devices with huge potential. The emergence of intelligent personal assistants (IPAs) is one of such potential example.

Testing and verification of healthcare information systems is a challenging and important issue since faults in these critical systems may lead to loss of lives, and in the best cases, loss of money and reputations. However, due to the complexity of these systems, and the increasing demand for new products and new technologies in this domain, there are several methods and technologies being used for testing these systems.

The future of ambient assisted living (AAL) especially eHealthcare almost depends on the smart objects that are part of the Internet of things (IoT). In our AAL scenario, these objects collect and transfer real-time information about the patients to the hospital server with the help of Wireless Mesh Network (WMN). Due to the multi-hop nature of mesh networks, it is possible for an adversary to reroute the network traffic via many denial of service (DoS) attacks, and hence affect the correct functionality of the mesh routing protocol.

Cloud computing has appeared to be state of the art in the world of Information Technology especially in healthcare systems due to its innovative computing deployment model as a source of utility for users. However, many healthcare organizations are disinclined to adapt cloud computing due to security shortcoming associated with its infrastructure and many of them are still unaddressed.
