Abstract:
Side-channel cryptanalysis exploits physical information leakage from
cryptographic devices to undermine their security. Most side-channel
attacks require special measurement equipment and are thus limited in
applicability.
This talk will present two side channels that can be exploited in many
settings without special equipment. First, CPU cache contention leaks
information on memory access patterns in several ways. Second,
acoustic emanations from electronic circuit components can be
information-bearing and are often detectable by a plain
microphone. Applications of these side channels to RSA and AES will be
shown.
In some common cases these attacks can be carried out by software
within the target computer, allowing an unprivileged process to glean
secret information from privileged ones without any explicit
interaction. This raises new challenges for multiuser, partitioned and
sandboxed environments.
Joint work with Dag Arne Osvik and Adi Shamir.
