The political career of Carlos Menem, Argentina’s president from 1989 to 1999, provides an easy chart for Latin America’s own embrace and rejection of economic policies that emphasized free trade and privatization over the

New Lower Bounds for Privacy in Communication Protocols,y and want to compute . for some fixed function . with the least amount of communication. Recently people have revisited the question of the privacy of such protocols: is it possible for Alice and Bob to compute . without revealing too much information about their inputs? There are two types of priv

On the Transmit Beamforming for MIMO Wiretap Channels: Large-System Analysis,. In this work, we consider MIMO wiretap channels in a fast fading environment, for which the overall performance is characterized by the ergodic MIMO secrecy rate. Unfortunately, the direct solution to finding ergodic secrecy rates is prohibitive due to the expectations in the rates expressions in

,Information Theoretic Security for Encryption Based on Conditional Rényi Entropies,ut also on the definitions of conditional Rényi entropies and the related information theoretic inequalities. First, we revisit conditional Rényi entropies, and clarify what kind of properties are required and actually satisfied. Then, we propose security criteria based on Rényi entropies, which sug

Insider-Proof Encryption with Applications for Quantum Key Distribution,essage. This prevents an insider, who has access to secret keys and the capability of choosing messages to be sent on the channel, from signalling to someone who can read the ciphertexts. We give a construction for approximately insider-proof private channels using 2-universal hash functions..Quantu
