We introduce HAIL (High-Availability and Integrity Layer), a distributed cryptographic system
that allows a set of servers to prove to a client that a stored file is intact and retrievable. HAIL …

Conventional software implementations of cryptographic algorithms are totally insecure
where a hostile user may control the execution environment, or where co-located with …

We describe a message authentication algorithm, UMAC, which can authenticate messages
(in software, on contemporary machines) roughly an order of magnitude faster than current …

In this work we perform the first comprehensive study of physical-layer identification of RFID
transponders. We propose several techniques for the extraction of RFID physical-layer …

This paper discusses key recovery and universal forgery attacks on several MAC algorithms
based on universal hash functions. The attacks use a substantial number of verification …

We consider the question of adaptive security for two related cryptographic primitives: all-or-
nothing transforms and exposure-resilient functions. Both are concerned with retaining …

Universal hash families and the leftover hash lemma, and applications to cryptography and
computing Page 1 Universal hash families and the leftover hash lemma, and applications to …

Universal hash functions are commonly used primitives for fast and secure message
authentication in the form of message authentication codes or authenticated encryption with …

(57) ABSTRACT A client device or other processing device comprises a file encoding
module, with the file encoding module being con figured to separate a file into a plurality of …

Quantum key distribution (QKD) offers a very strong property called everlasting security,
which says if authentication is unbroken during the execution of QKD, the generated key …
