ECCbAS: An ECC based authentication scheme for healthcare IoT systems

Smart technology is a concept for efficiently managing smart things such as vehicles, buildings, home appliances, healthcare systems and others, through the use of networks and the Internet. Smart architecture makes use of technologies such as the Internet of Things (IoT), fog computing, and cloud computing. The Smart Medical System (SMS), which is focused on communication networking and sensor devices, is one of the applications used in this architecture. In a smart medical system, a doctor uses cloud-based applications such as mobile devices, wireless body area networks, and other cloud-based apps to provide online therapy to patients. Consequently, with the advancement and growth of IoT and 6G wireless technology, privacy and security have emerged as two of the world’s most important issues. Recently, Sureshkumar et al. proposed an authentication scheme for medical wireless sensor networks (MWSN) by using an Elliptic Curve Cryptography (ECC) based lightweight authentication protocol and claimed that it provides better security for smart healthcare systems. This paper will demonstrate that this protocol is susceptible to attacks such as traceability, integrity contradiction, and de-synchronization with the complexity of one run of the protocol and a success probability of one. Furthermore, we also propose an ECC based authentication scheme called ECCbAS to address the Sureshkumar et al. protocol’s vulnerabilities and demonstrate its security using a variety of non-formal and formal methods.     

Always connected,but are smart mobile users getting more security savvy? A survey of smart mobile device users

Smart mobile devices are a potential attack vector for cyber criminal activities. Two hundred and fifty smart mobile device owners from the University of South Australia were surveyed. Not surprisingly, it was found that smart mobile device users in the survey generally underestimated the value that their collective identities have to criminals and how these can be sold. For example, participants who reported jail-breaking/rooting their devices were also more likely to exhibit risky behaviour (e.g. downloading and installing applications from unknown providers), and the participants generally had no idea of the value of their collective identities to criminals which can be sold to the highest bidder. In general, the participants did not understand the risks and may not have perceived cyber crime to be a real threat. Findings from the survey and the escalating complexities of the end-user mobile and online environment underscore the need for regular ongoing training programs for basic online security and the promotion of a culture of security among smart mobile device users. For example, targeted education and awareness programmes could be developed to inform or educate smart mobile device users and correct misconceptions or myths in order to bring about changes in attitudes and usage behaviour (e.g. not taking preventative measures such as strong passwords to protect their devices). Such initiatives would enable all end users (including senior University management who use such devices to access privileged corporate data and accounts) to maintain current knowledge of the latest cyber crime activities and the best cyber security protection measures available.

Android mobile VoIP apps: a survey and examination of their security and privacy

Voice over Internet Protocol (VoIP) has become increasingly popular among individuals and business organisations, with millions of users communicating using VoIP applications (apps) on their smart mobile devices. Since Android is one of the most popular mobile platforms, this research focuses on Android devices. In this paper we survey the research that examines the security and privacy of mVoIP published in English from January 2009 to January 2014. We also examine the ten most popular free mVoIP apps for Android devices, and analyse the communications to determine whether the voice and text communications using these mVoIP apps are encrypted. The results indicate that most of the apps encrypt text communications, but voice communications may not have been encrypted in Fring, ICQ, Tango, Viber, Vonage, WeChat and Yahoo. The findings described in this paper contribute to an in-depth understanding of the potential privacy risks inherent in the communications using these apps, a previously understudied app category. Six potential research topics are also outlined.     

Robust one-time password authentication scheme using smart card for home network environment

Due to the exponential growth of the Internet users and wireless devices, interests on home networks have been enormously increased in recent days. In digital home networks, home services including remote access and control to home appliances as well as services offered by service providers are alluring. However, the remote control services cause digital home networks to have various security threats. Hence, for digital home networks, robust security services, especially remote user authentication, should be considered. This paper presents a robust and efficient authentication scheme based on strong-password approach to provide secure remote access in digital home network environments. The proposed scheme uses lightweight computation modules including hashed one-time password and hash-chaining technique along with low-cost smart card technology. It aims to satisfy several security requirements including stolen smart card attack and forward secrecy with lost smart card as well as functional requirements including no verification table and no time synchronization. Comparing with the existing representative schemes, it can be validated that the proposed scheme is more robust authentication mechanism having better security properties. We have conducted formal verification of the proposed scheme.
