Cryptographic Combinatorial Clock-Proxy Auctions
We present a cryptographic protocol for conducting efficient, provably correct and secrecy-preserving combinatorial clock-proxy auctions. The “clock phase” functions as a trust...

Interactive Locking, Zero-Knowledge PCPs, and Unconditional Cryptography
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 fo...

Conversion and Proxy Functions for Symmetric Key Ciphers
As a general design criterion, a symmetric key cipher should not be closed under functional composition due to the implications on the security of the cipher. However, there are s...
