Zigbee is an IEEE 802.15.4-based specification for low-power wireless mesh networks. Being a protocol with several known vulnerabilities, it continues to attract extensive research interest due to its potential applications in the Internet-of-Things (IoT). One of Zigbee's weak points lies in the network coordinator's initial handshake with a joining device, which is unencrypted. Our paper proposes...
With the recent advances in SDN-based technologies, there is a great interest from different communities to exploit SDN for their domain needs. One of such domains is Smart Grid where the underlying network is going through a massive upgrade to enable not only faster and reliable communications but also convenient control. To this end, SDN can be a viable option to provide resilience in Smart Grid...
The proliferation of cloud computing over the past several years has led to a variety of new use cases and enabling technologies for enterprise and consumer applications. Increased reliance on cloud-based platforms has also necessitated an increased emphasis on securing the services and data hosted within those platforms. From a security standpoint, an advantage of cloud platforms over traditional...
Multi-factor authentication (MFA) is an approach to user validation that requires the presentation of two or more authentication factors. Given the popularity of cloud systems, MFA systems become vital in authenticating users. However, MFA approaches are highly intrusive and expose users' sensitive information to untrusted cloud servers that can keep physically identifying elements of users, long...
Wireless Sensor Networks (WSNs) are rapidly gaining popularity in various critical domains like health care, critical infrastructure, and climate monitoring, where application builders have diversified development needs. Independent of the functionalities provided by the WSN applications, many of the developers use visualization, simulation, and programming tools. However, these tools are designed...
