Black Hat Europe 2014,

(60 minutes).
Many computer systems use protective mechanisms, which are mathematically secure but physically vulnerable. In this talk, I will survey the development of such side channel attacks since the late 1990's, and describe various examples of devastating attacks on widely deployed systems. In the last part of the talk, I will describe some recently developed (and previously unpublished) techniques which can be used by an outside attacker to establish long range (>1 kilometer) bidirectional communication with a top-secret computer system which contains only standard untampered hardware components, is completely air gapped, and is perfectly shielded from TEMPEST attacks.

Adi Shamir is currently The Borman Professor of Applied Mathematics at the Weizmann Institute of Science. Shamir's main area of research is cryptography where he has made significant contributions. Among his many achievements, Adi Shamir is widely recognized for co-inventing the RSA algorithm (along with Ronald L. Rivest and Leonard M. Adleman), bringing the "S" to the acronym "RSA." He is also the co-inventor of the Feige-Fiat-Shamir identification scheme (along with Uriel Feige and Amos Fiat) and is credited with creating the Shamir secret sharing scheme. Shamir is also known for the breaking of the Merkle-Hellman knapsack cryptosystem, visual cryptography, and the TWIRL and TWINKLE factoring devices.
Most recently he has developed (along with his students and colleagues) new practical cryptographic paradigms such as broadcast encryption, ring signatures and T-functions; new cryptanalytic attacks against block ciphers, stream ciphers, and number theoretic schemes; and new protective techniques against side channel attacks such as power analysis.
Shamir received a BSc degree in mathematics from Tel Aviv University in 1973 and obtained his MSc and PhD degrees in Computer Science from the Weizmann Institute in 1975 and 1977 respectively. After a year of postdoctoral research at the University of Warwick, Shamir worked at MIT from 1977 to 1980. Following his time at MIT, Shamir became a faculty member of Mathematics and Computer Science at the Weizmann Institute.
