A number of works have investigated using tamper-proof hardware tokens as tools to
achieve a variety of cryptographic tasks. In particular, Goldreich and Ostrovsky considered …

Secure multiparty computation (MPC) enables privacy-preserving collaborative computation
over sensitive data held by multiple mutually distrusting parties. Unfortunately, in the most …

Design of secure systems can often be expressed as ensuring that some property is
maintained at every step of a distributed computation among mutually-untrusting parties …

Abstract Physically Uncloneable Functions (PUFs)[28] are noisy physical sources of
randomness. As such, they are naturally appealing for cryptographic applications, and have …

In this paper, we initiate a study of zero knowledge proof systems in the presence of side-
channel attacks. Specifically, we consider a setting where a cheating verifier is allowed to …

Motivated by the question of basing cryptographic protocols on stateless tamper-proof
hardware tokens, we revisit the question of unconditional two-prover zero-knowledge proofs …

We study the problem of constructing concurrently secure computation protocols in the plain
model, where no trust is required in any party or setup. While the well established UC …

Abstract We consider Secure Function Evaluation (SFE) in the client-server setting where
the server issues a secure token to the client. The token is not trusted by the client and is not …

We present a constant-round unconditional black-box compiler that transforms any ideal (ie,
statistically-hiding and statistically-binding) straight-line extractable commitment scheme …
