Oblivious Transfer Is Symmetric
We show that oblivious transfer of bits from A to B can be obtained from a single instance of the same primitive from B to A. Our reduction is perfect and shows that oblivious tran...

A Provable-Security Treatment of the Key-Wrap Problem
Abstract. We give a provable-security treatment for the key-wrap problem, providing definitions, constructions, and proofs. We suggest that key-wrap's goal is security in the ...

Composition Implies Adaptive Security in Minicrypt
To prove that a secure key-agreement protocol exists one must at least show P = NP. Moreover any proof that the sequential composition of two non-adaptively secure pseudorandom fun...

Cryptography in Theory and Practice: The Case of Encryption in IPsec
Abstract. This paper studies the gaps that exist between cryptography as studied in theory, as defined in standards, as implemented by software engineers, and as actually consumed ...

Language Modeling and Encryption on Packet Switched Networks
The holy grail of a mathematical model of secure encryption is to devise a model that is both faithful in its description of the real world, and yet admits a construction for an en...

Luby-Rackoff Ciphers from Weak Round Functions?
The Feistel-network is a popular structure underlying many block-ciphers where the cipher is constructed from many simpler rounds, each defined by some function which is derived fr...

Learning a Parallelepiped: Cryptanalysis of GGH and NTRU Signatures
Abstract. Lattice-based signature schemes following the GoldreichGoldwasser-Halevi (GGH) design have the unusual property that each signature leaks information on the signer's...

Sequential Aggregate Signatures and Multisignatures Without Random Oracles
We present the first aggregate signature, the first multisignature, and the first verifiably encrypted signature provably secure without random oracles. Our constructions derive f...

Polling with Physical Envelopes: A Rigorous Analysis of a Human-Centric Protocol
We propose simple, realistic protocols for polling that allow the responder to plausibly repudiate his response, while at the same time allow accurate statistical analysis of poll ...
