Founding Cryptography on Tamper-Proof Hardware Tokens
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 the ...

Public-Key Cryptographic Primitives Provably as Secure as Subset Sum
Abstract. We propose a semantically-secure public-key encryption scheme whose security is polynomialtime equivalent to the hardness of solving random instances of the subset sum pr...

New Techniques for Dual System Encryption and Fully Secure HIBE with Short Ciphertexts
We construct a fully secure HIBE scheme with short ciphertexts. The previous construction of Boneh, Boyen, and Goh was only proven to be secure in the selective model, under a non...

Threshold Decryption and Zero-Knowledge Proofs for Lattice-Based Cryptosystems
We present a variant of Regev’s cryptosystem first presented in [Reg05], but with a new choice of parameters. By a recent classical reduction by Peikert we prove the scheme sema...

Leakage-Resilient Signatures
The strongest standard security notion for digital signature schemes is unforgeability under chosen message attacks. In practice, however, this notion can be insufficient due to ...

A Domain Extender for the Ideal Cipher
We describe the first domain extender for ideal ciphers, i.e. we show a construction that is indifferentiable from a 2n-bit ideal cipher, given a n-bit ideal cipher. Our construc...

Rationality in the Full-Information Model
We study rationality in protocol design for the full-information model, a model characterized by computationally unbounded adversaries, no private communication, and no simultanei...

On Complete Primitives for Fairness
Abstract. For secure two-party and multi-party computation with abort, classification of which primitives are complete has been extensively studied in the literature. However, for...
