1998 Conferences

1st CACR Information Security Workshop

Paul Kocher, Cryptography Research

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.

Speaker Bio
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.
