Impossibility of Black-Box Simulation Against Leakage Attacks

In this work, we show how to use the positive results on succinct argument systems to prove impossibility results on leakage-resilient black-box zero knowledge. This recently proposed notion of zero knowledge deals with an adversary that can make leakage queries on the state of the prover. Our result holds for black-box simulation only and we also give some insights on the non-black-box case. A...

Studies in Program Obfuscation

Program obfuscation is the software analog to the problem of tamper-proofing hardware. The goal of program obfuscation is to construct a compiler, called an “obfuscator,” that garbles the code of a computer program while maintaining its functionality. Commercial products exist to perform this procedure, but they do not provide a rigorous security guarantee. Over the past decade, program obfusca...

A Study of Separations in Cryptography: New Results and New Models

Title of dissertation: A STUDY OF SEPARATIONS IN CRYPTOGRAPHY: NEW RESULTS AND NEW MODELS Arkady Yerukhimovich, Doctor of Philosophy, 2011 Dissertation directed by: Professor Jonathan Katz Department of Computer Science For more than 20 years, black-box impossibility results have been used to argue the infeasibility of constructing certain cryptographic primitives (e.g., key agreement) from oth...

Practical Leakage-Resilient Symmetric Cryptography

Leakage resilient cryptography attempts to incorporate sidechannel leakage into the black-box security model and designs cryptographic schemes that are provably secure within it. Informally, a scheme is leakage-resilient if it remains secure even if an adversary learns a bounded amount of arbitrary information about the schemes internal state. Unfortunately, most leakage resilient schemes are u...

Limits on the Power of Zero-Knowledge Proofs in Cryptographic Constructions

For over 20 years, black-box impossibility results have been used to argue the infeasibility of constructing certain cryptographic primitives (e.g., key agreement) from others (e.g., one-way functions). A widely recognized limitation of such impossibility results, however, is that they say nothing about the usefulness of (known) nonblack-box techniques. This is unsatisfying, as we would at leas...
