Protecting File Systems with Transient Authentication

Mark D. Corner, Brian D. Noble
2005 Wireless networks  
This tension between usability and security is eliminated through Transient Authentication, in which a small hardware token continuously authenticates the user's presence to the laptop over a short-range  ...  Laptops are vulnerable to theft, greatly increasing the likelihood of exposing sensitive files. Unfortunately, storing data in a cryptographic file system does not fully address this problem.  ...  We resolve this tension with Transient Authentication, in which the user wears a small authentication token.  ...

The case for transient authentication

Brian D. Noble, Mark D. Corner
2002 Proceedings of the 10th workshop on ACM SIGOPS European workshop: beyond the PC - EW10  
This paper presents the four principles of transient authentication, our experience applying the model to a cryptographic file system, and our plans for extending the model to other services and applications  ...  Such persistent authentication is inappropriate for mobile and ubiquitous systems, because associations between people and devices are fleeting. To address this, we propose transient authentication.  ...  Example: Protecting File Systems To validate this approach, we have built ZIA, a cryptographic file system employing transient authentication.  ...

Protecting applications with transient authentication

Mark D. Corner, Brian D. Noble

Mobile Device Security Using Transient Authentication

A.J. Nicholson, M.D. Corner, B.D. Noble
2006 IEEE Transactions on Mobile Computing  
Transient Authentication lifts the burden of authentication from the user by use of a wearable token that constantly attests to the user's presence.  ...  Existing schemes for securing data either do not protect the device after it is stolen or require bothersome reauthentication.  ...  We have ported the Transient Authentication software to protect both x86-based devices (such as laptops) and iPAQ handhelds with ARM processors.  ...

PinUP: Pinning User Files to Known Applications

William Enck, Patrick McDaniel, Trent Jaeger
2008 2008 Annual Computer Security Applications Conference (ACSAC)  
In this paper, we take advantage of this reality by developing protection mechanisms that "pin" user files to the applications that may use them.  ...  Because system protections do not differentiate applications, any malcode present in the downloaded software can compromise or otherwise leak all user data.  ...  This functionality is similar to how the root user in UNIX systems is treated with respect to user file system protections. Applications within agid 0 must Figure 4.  ...
