[HGI-News-de] HGI Kolloquium - Zwei Vortragstermine diese Woche: Mi. und Do., 27. + 28..10.!

Mo Okt 25 11:15:51 CEST 2010

Hallo,

im Rahmen des HGI Kolloquiums "Aktuelle Themen der IT-Sicherheit" wird am kommenden *Mittwoch* der folgende Vortrag angeboten:

Wayne Burleson (University of Massachusetts Amherst)

**Hardware Security in Nanometer CMOS**

Termin:
Mittwoch, den 27. Oktober um 11.00 Uhr (*s.t.*)
Raum: wird noch auf der HGI-Kolloquiums-Seite bekannt gegeben

Abstract: 
As computer systems become ubiquitous, security concerns are paramount. Security systems are
typically heavily layered but ultimately rely on low-level hardware primitives and assumptions.
Lightweight applications such as RFID, Smart cards and Smart dust require very lightweight security
primitives that can withstand a range of attacks. In this talk, we explore the design of very lightweight
True Random Number Generators and Chip Identification circuits in CMOS technologies at 45nm and
below. We also show side-channel vulnerabilities that arise in advanced CMOS technologies due to
process variation and noise. Some existing countermeasures are shown to be weak in advanced
technologies, and new countermeasures are proposed. We will discuss hardware Trojans and their
potential impact on semiconductor security. Finally, we will discuss applications in Transportation
Payment Systems and Implantable Medical Devices, among others. This work is supported by NSF, SRC,
Intel and Cisco and also gives insight into methods for statistical design beyond security.

Am kommenden *Donnerstag* wird der folgende Vortrag angeboten:

Falk Schellenberg (Ruhr-Universität Bochum)

**Comparing Power and Electromagnetic Analysis of Embedded Devices****

Termin:
Donnerstag, den 28. Oktober um 11.00 Uhr (*s.t.*)
Raum: ID 03/445

Abstract: 
Implementation attacks describe the extraction of information from the
physical behaviour of a target device. As shown by various authors,
regardless of the mathematical security of a cryptographic algorithm, there
may be a leak of some information, which reveals, e.g., a secret key.
However, the way of measuring this information introduces several crucial
parameters which decide about the efficiency or success of revealing the
secret key of a target device. In this thesis, we compare different so
called side-channels, namely power consumption and electromagnetic
emanation, and evaluate methods and parameters for a differential
correlation analysis. Furthermore, we capture the electromagnetic emanation
with various probes at different positions, e.g., in the near-field and on
the surface of the integrated circuit. In addition, we compare the practical
influence of different measurement parameters, e.g., sample rate and
quantisation, and, in order to improve the results, different preprocessing
techniques, e.g., alignment, transformation to the frequency domain, and
peak extraction. Two popular 8 bit microcontrollers running the Advanced
Encryption Standard with a well-known vulnerability are chosen as target
devices. Yet, our results can be universally adapted to other devices and
ciphers as well.

Interessierte sind herzlich eingeladen!
