Virtual Grey-Boxes Beyond Obfuscation: A Statistical Security Notion for Cryptographic Agents
cryptographic agents obfuscation simulation-based security
2016/12/10
We extend the simulation-based definition of Virtual Grey Box (VGB) security -- originally proposed for obfuscation (Bitansky and Canetti, 2010) -- to a broad class of cryptographic primitives. These ...

In the context of Universal Composability, we introduce the concept of universal
environments and simulators. Then, Universal Composability is equivalent to Universal
Composability wrt. universal en...

We investigate the definition of statistical security (i.e., security against unbounded adversaries) in the framework of reactive simulatability. This framework allows to
formulate and analyze multi-...
