1st CACR Information Security Workshop
Differential power analysis.
Recent work at Cryptography Research has found that the amount of power
used by many cryptographic devices is correlated to the operations they
perform, and that these correlations can be analyzed to recover
secret keys. Simple Power Analysis (SPA) and Differential Power Analysis
(DPA) are methods for determining secret keys using power consumption
measurements. This talk will overview SPA and DPA and related issues that
need to be considered when designing cryptosystems.
Paul Kocher has gained an international reputation for his consulting
work and academic research in cryptography. His Cryptography Research
team has provided applied cryptographic solutions to clients ranging
from start-ups to Fortune 500 companies.
An active contributor to major conferences and standards bodies, Paul
has designed many cryptographic applications and protocols including
SSL v3.0. His development of timing attacks to break RSA and other
algorithms received front-page coverage in the New York Times.
More recently he has led research to develop Differential Power Analysis
and designs for securing smart cards and other devices against these
attacks, as well as to design a record-breaking DES Key Search machine.
Paul also currently serves as Chief Scientist to ValiCert, Inc., a company
implementing high-performance certificate revocation technologies. Paul
holds a B.S. degree from Stanford University.
