abstract Rafail Ostrovskyy Ramarathnam Venkatesanz Moti Yungx Secure commitment is a primitive enabling information hiding, which is one of the most basic tools in cryptography. S...
We present an implementation of the protocol of Lindell and Pinkas for secure two-party computation which is secure against malicious adversaries [13]. This is the first running sy...
Securely authenticating a human user without assistance from any auxiliary device in the presence of powerful passive adversaries is an important and challenging problem. Passive ...
Abstract. In this paper we consider commitment schemes that are secure against concurrent man-in-the-middle (cMiM) attacks. Under such attacks, two possible notions of security for...

We consider the problem of basing Oblivious Transfer (OT) and Bit Commitment (BC), with information theoretic security, on seemingly weaker primitives. We introduce a general model...
