It is finally here, THE END…

…of my academic carrear ;)

Today I gave my last talk at the SECRYPT conference in Sevilla. After my PhD thesis defense last Wednesday, this had been my first scientific presentation as Dr. Lackner!!! But it has obviously also been the last ;)

As most of you know, I started in Product Management at NXP Semiconductors. A job which is suspected to carry me far away from IT research. But as James Bond said, “Never say never!”.

For everybody interested, this is my presentation at SECRYPT:

SECRYPT2011 Presentation on Prezi

And this is the presentation of my PhD thesis defense:

http://sky.scitech.qut.edu.au/~boydc/

*Titel:*”DoS-resistant key exchange: models and mechanisms”

*Zeit:* Mittwoch, 13.7.2011, 14:30 Uhr

*Ort:* Seminarraum IAIK, Inffeldgasse 16a/EG

Wir freuen uns auf Ihr Kommen!

Das Dekansteam

Abstract:

Security models for key exchange have been around for many years, but

only recently have started to include consideration of denial-of-service

attacks. This talk will consider security models for client puzzles and

in particular introduce a new model presented at CT-RSA 2011. The new

model incorporates the possibility that an adversary may attack multiple

puzzles simultaneously. In addition we will consider the notion of

gradual authentication as applied to key exchange and introduce a new

mechanism combining client puzzles and digital signatures with fast

verification. This is joint work with Juan Gonzalez, Lakshmi Kuppusamy,

Jothi Rangasamy and Douglas Stebila. *

PhD Thesis accepted for submission!

After incorporating the final comments of my assessors Vincent Rijmen and Colin Boyd, I was permitted to officially submit my PhD thesis last week!

The official defense will be held on July 13th 2011 at 11:00 am at the Seminarraum of the IAIK at TU Graz.

Looks like this chapter is finally coming to an end :-D

Keynote by Gene Tsudik at AISC2011 in Perth tomorrow

I am looking forward to hear the keynote by Professor Gene Tsudik at the AISC tomorrow morning at Curtain University Pert, Australia.

My talk about IEEE 802.11 Chipset Fingerprinting by the Measurement of Timing Characteristics will take place right after the keynote. Would be great if you guys could make it ;)

Usable Security: the case of user-aided pairing of wireless devices

Abstract
‘Secure device pairing’ is the process of bootstrapping a secure channel between two or more previously unassociated personal devices over a (usually wireless) human-imperceptible communication channel. Lack of prior security context and absence of common trust infrastructure open the door for so-called “Man-in-the-Middle” (or “Evil Twin”) attacks. Mitigation of these attacks requires user involvement in the device pairing process. This research direction is both important and timely, since it considers usability in one of the few security-relevant settings that involves a wide range of users. Prior research yielded a number of interesting methods utilizing various auxiliary human-perceptible channels, e.g., visual, acoustic and tactile. These methods engage the user in authenticating information exchanged over human-imperceptible channels, thus countering attacks and forming the basis for secure device pairing.

This talk will begin by summarizing notable secure device pairing techniques, comparing and contrasting their advantages, shortcomings and limitations. Then, we present a comprehensive and comparative evaluation (based on both on usability and security) of these methods. Results identify methods best-suited for a given combination of devices and human abilities. Next, we consider the group setting where more than two unfamiliar devices need to be associated in order to set up a secure communication context. We then report on a usability study that compares several potential group pairing techniques. We conclude with some unresolved issues and potential avenues for future research.

Biography Gene Tsudik is a Professor of Computer Science at the University of California, Irvine (UCI). He obtained his PhD in Computer Science from USC in 1991. Before coming to UCI in 2000, he was at IBM Zurich Research Laboratory (1991-1996) and USC/ISI (1996-2000). Over the years, his research interests included many topics in security and applied cryptography. He currently serves as Director of Secure Computing and Networking Center (SCONCE) and Vice-Chair of the Computer Science Department. Since 2009, he is the Editor-in-Chief of ACM Transactions on Information and Systems Security (TISSEC).

Paper submitted to IJNS

I just submitted a paper with the title “A Comparison of Security in Wireless Network Standards with a Focus on Bluetooth, WiFi and WiMAX” to the International Journal of Network Security.

Abstract. As wireless networks are finally coming of age, peo- ple and organizations start to implement critical applications and infrastructures based on them. As most wireless network standards have been designed with security as an afterthought, severe security shortcomings were the results and several improvements and amendments were necessary to fix the worst. Founded on a series of insecure implementations and design faults, recent standards and amendments show some improvements. To cover personal area, local area and wide area wireless networks, the following standards have been chosen as examples: IEEE 802.15.1 Bluetooth, IEEE 802.11 WiFi and IEEE 802.16 WiMAX. This article provides a detailed overview, analysis and discussion of state-of- the-art security mechanisms in wireless networks and briefly presents their development and history allowing the reader to quickly gain detailed insight into the topic.
