Tamper and Leakage Resilience in the Split-State Model
It is notoriously difficult to create hardware that is immune from side channel and tampering attacks. A lot of recent literature, therefore, has instead considered algorithmic de...

Crowd-Blending Privacy
We introduce a new definition of privacy called crowd-blending privacy that strictly relaxes the notion of differential privacy. Roughly speaking, k-crowd blending private saniti...

Black-Box Constructions of Composable Protocols without Set-Up
Abstract. We present the first black-box construction of a secure multiparty computation protocol that satisfies a meaningful notion of concurrent security in the plain model (wi...

Secret Sharing Schemes for Very Dense Graphs
A secret-sharing scheme realizes a graph if every two vertices connected by an edge can reconstruct the secret while every independent set in the graph does not get any informatio...

Tweakable Blockciphers with Beyond Birthday-Bound Security
Liskov, Rivest and Wagner formalized the tweakable blockcipher (TBC) primitive at CRYPTO’02. The typical recipe for instantiating a TBC is to start with a blockcipher, and then b...

Securing Circuits against Constant-Rate Tampering
We present a compiler that converts any circuit into one that remains secure even if a constant fraction of its wires are tampered with. Following the seminal work of Ishai et al. ...

Homomorphic Evaluation of the AES Circuit
We describe a working implementation of leveled homomorphic encryption (without bootstrapping) that can evaluate the AES-128 circuit in three different ways. One variant takes und...
