USB 3.0 Promoter Group Defines Authentication Protocol for USB Type-C™
PRESS RELEASE CONTACTS: Brad Saunders Liz Nardozza USB 3.0 Promoter Group USB-IF PR +1 503-264-0817 +1 503-619-5224 [email protected] [email protected] USB 3.0 Promoter Group Defines Authentication Protocol for USB Type-C™ Specification defines policy for product OEMs to mitigate risks from non-compliant devices Shenzhen, China and Beaverton, OR, USA – April 13, 2016 – The USB 3.0 Promoter Group today announced the USB Type-C™ Authentication specification, defining cryptographic-based authentication for USB Type-C™ chargers and devices. Using this protocol, host systems can confirm the authenticity of a USB device or USB charger, including such product aspects as the descriptors/capabilities and certification status. All of this happens right at the moment a wired connection is made – before inappropriate power or data can be transferred. USB Type-C™ Authentication empowers host systems to protect against non-compliant USB Chargers and to mitigate risks from maliciously embedded hardware or software in USB devices attempting to exploit a USB connection. For a traveler concerned about charging their phone at a public terminal, their phone can implement a policy only allowing charge from certified USB chargers. A company, tasked with protecting corporate assets, can set a policy in its PCs granting access only to verified USB storage devices. “USB is well-established as the favored choice for connecting and charging devices,” said Brad Saunders, USB 3.0 Promoter Group Chairman. “In support of the growing USB Type-C ecosystem, we anticipated the need for a solution extending the integrity of the USB interface. -
INTEGRIKEY: Integrity Protection of User Input for Remote Configuration of Safety-Critical Devices
INTEGRIKEY: Integrity Protection of User Input for Remote Configuration of Safety-Critical Devices Aritra Dhar Der-Yeuan Yu Kari Kostiainen ETH Zurich¨ ABB Corporate Research ETH Zurich¨ [email protected] [email protected] [email protected] Srdjan Capkunˇ ETH Zurich¨ [email protected] Abstract Various safety-critical devices, such as industrial control systems, medical devices, and home automation systems, are configured through web interfaces from remote hosts that are standard PCs. The communication link from the host to the safety-critical device is typically easy to protect, but if the host gets compromised, the adversary can manipulate any user-provided configuration settings with severe consequences including safety violations. In this paper, we propose INTEGRIKEY, a novel system for user input integrity protection in compromised host. The user installs a simple plug-and-play device between the input peripheral and the host. This device Figure 1: Example configuration page. Screenshot from the observes user input events and sends a trace of them ControlByWeb x600m [10] I/O server configuration page. to the server that compares the trace to the application payload received from the untrusted host. To prevent programmer device) is easy to protect through standard subtle attacks where the adversary exchanges values means such as a TLS connection [12]. However, if from interchangeable input fields, we propose a labeling the host platform gets compromised—as standard PC scheme where the user annotates input values. We built platforms so often do—the adversary can manipulate any a prototype of INTEGRIKEY, using an embedded USB user-provided configuration settings. -
