Vulnerability Bounds and Leakage Resilience of Blinded Cryptography under Timing Attacks
—We establish formal bounds for the number of min-entropy bits that can be extracted in a timing attack against a cryptosystem that is protected by blinding, the state-of-the art...

Cryptography by Cellular Automata or How Fast Can Complexity Emerge in Nature?
Computation in the physical world is restricted by the following spatial locality constraint: In a single unit of time, information can only travel a bounded distance in space. A ...

Adaptively Secure Feldman VSS and Applications to Universally-Composable Threshold Cryptography
We propose the first distributed discrete-log key generation (DLKG) protocol from scratch which is adaptively-secure in the non-erasure model, and at the same time completely avoi...

Towards Security Notions for White-Box Cryptography
Abstract. While code obfuscation attempts to hide certain characteristics of a program independently of an application, white-box cryptography (WBC) specifically focuses on softwa...
