Additive Manufacturing (AM, or 3D printing) is an emerging manufacturing technology with far-reaching implications. AM is increasingly used to produce functional parts, including components for safety-critical systems. However, AM’s unique capabilities and dependence on computerization raise a concern that an AM generated part could be sabotaged by a(More)
Additive Manufacturing (AM, or 3D printing) is a novel manufacturing technology that is being adopted in industrial and consumer settings. However, the reliance of this technology on computerization has raised various security concerns. In this paper we address sabotage via tampering with the 3D printing process. We present an object verification system(More)
Considering the exponential increase of Internet of Things (IoT) devices there is also unforeseen vulnerabilities associated with these IoT devices. One of the major problems in the IoT is the security testing and analysis due to the heterogeneous nature of deployments. Currently, there is no mechanism that performs security testing for IoT devices in(More)
The exponential increase of Internet of Things (IoT) devices have resulted in a range of new and unanticipated vulnerabilities associated with their use. IoT devices from smart homes to smart enterprises can easily be compromised. One of the major problems associated with the IoT is maintaining security; the vulnerable nature of IoT devices poses a(More)
Many printers nowadays support Wi-Fi connectivity. Some organizations opt to disable their printer's wireless connectivity, others are not aware at all that it is enabled and some enable it in an encrypted form. In this paper we demonstrate how an application called "pFaker" running on a mobile device or smart watch can be used to mimic a printer's Wi-Fi(More)
