Abstract talk Jasper van Woudenberg, From space rays to laser beams: Fault
injection in practice

Fault injection attacks are moving into the realm of embedded systems:
secure memory 'readers' that use glitching to bypass security mechanisms
are commercially available, and more recently Xbox 360 code security was
broken by glitching the processor's reset line. Fault injection attacks
aim to change the behavior of a device; e.g. to bypass authentication or
extract secret information. We explain the fundamentals of fault
injection, covering their history, the tools used for their execution,
Differential Fault Analysis and other attacks that we execute in practice.

Abstract talk Ludo Tolhuizen, Towards fully collusion-resistant ID-based
establishment of pairwise keys

We discuss the problem of securely establishing a symmetric key to be
applied in a symmetric key algorithm.  This classical problem is still
relevant and of paramount importance both in existing computer networks
and new large-scale ubiquitous systems comprising resource-constrained
devices. Identity(ID)-based pairwise key agreement allows for the
generation of a common key between two parties from secret keying material
owned by the first party and the identity of the second one. However,
existing methods, e.g., based on polynomials, are prone to collusion
attacks.

We discuss a new key establishment scheme aiming at fully
collusion-resistant ID-based symmetric-key agreement. Our scheme, the
HIMMO algorithm, relies on two design concepts: Hiding Information and
Mixing Modular Operations. We show why attacks on ID-based symmetric key
agreement from literature, as well as some other attacks, cannot be
applied to HIMMO.  The simple logic of the HIMMO algorithm allows for very
efficient implementations in terms of both speed and memory.
