(2007-12-05)We put forward the notion of a verifiably secure device, in essence a stronger notion of secure computation, and achieve it in the ballot-box model. Verifiably secure devices1. Provide a perfect solution to the problem of ...

Verification of Semantic Commutativity Conditions and Inverse Operations on Linked Data Structures (2010-12-03)Commuting operations play a critical role in many parallel computing systems. We present a new technique for verifying commutativity conditions, which are logical formulas that characterize when operations commute. Because ...

(2004-05-17)Several studies have shown that wide-area Internet routing is fragile, with failures occurring for a variety of reasons. Routing fragility is largely due to the flexible and powerful ways in which BGP can be configured to ...

(2004-06-14)For the last several decades, computer architecture research has largely benefited from, and continues to be driven by ad-hoc benchmarking. Often the benchmarks are selected to represent workloads that architects believe ...

(2005-10-10)Future CMPs will have more cores and greater onchip cache capacity. The on-chip cache can either be divided into separate private L2 caches for each core, or treated as a large shared L2 cache. Private caches provide low ...

(2004-05-11)This paper describes a method for bringing two videos (recorded at different times) into spatiotemporal alignment, then comparing and combining corresponding pixels for applications such as background subtraction, compositing, ...
-
(2009-12-16)This paper introduces the video mesh, a data structure for representing video as 2.5D "paper cutouts." The video mesh allows interactive editing of moving objects and modeling of depth, which enables 3D effects and ...
-
(2012-07-23)This paper presents an updated version of Viewstamped Replication, a replication technique that handles failures in which nodes crash. It describes how client requests are handled, how the group reorganizes when a replica ...

(2004-02-26)One of the most significant challenges introduced by mobile networks is the difficulty in coping withthe unpredictable movement of mobile nodes. If, instead, the mobile nodes could be programmed totravel through the world ...

(2006-09-11)A trusted monotonic counter is a valuable primitive thatenables a wide variety of highly scalable offlineand decentralized applications that would otherwise be prone to replay attacks, including offline payment, e-wallets, ...
-
(2005-01-21)We define a programming abstraction formobile networks called the Virtual Stationary Automataprogramming layer, consisting of real mobile clients, virtualtimed I/O automata called virtual stationary automata(VSAs), and a ...

(2004-01-28)Recovering a volumetric model of a person, car, or other objectof interest from a single snapshot would be useful for many computergraphics applications. 3D model estimation in general is hard, andcurrently requires active ...

(2011-07-27)Recent trends in OS research have shown evidence that there are performance benefits to running OS services on different cores than the user applications that rely on them. We quantitatively evaluate this claim in terms ...
-
(2005-04-05)We present a simple, efficient, and self-contained construction of a wait-free regular register from Byzantine storage components. Our construction utilizes a novel building block, called 1-regular register, which can be ...

Was the Patient Cured? Understanding Semantic Categories and Their Relationships in Patient Records (2006-06-28)In this thesis, we detail an approach to extracting key information in medical discharge summaries. Starting with a narrative patient report, we first identify and remove information that compromises privacy (de-identifi ...

(2008-01-31)Applications that combine live data streams with embedded, parallel,and distributed processing are becoming more commonplace. WaveScriptis a domain-specific language that brings high-level, type-safe,garbage-collected ...

(2011-03-04)Excerpts from a talk given by Tomaso Poggio in Tübingen on the opening ofthe Werner Reichardt Centrun für Integrative Neurowissenschaften, December 8, 2008.

(2009-09-24)Decentralized systems, such as distributed hash tables, are subject to the Sybil attack, in which an adversary creates many false identities to increase its influence. This paper proposes a routing protocol for a distributed ...
-
(2011-02-01)We prove several decidability and undecidability results for the satisfiability/validity problem of formulas over a language of finite-length strings and integers (interpreted as lengths of strings). The atomic formulas ...

(2006-05-27)Distributed computing and live-action roleplaying share many of thesame fundamental problems, as live-action roleplaying games commonly include simulations carried out by their players.Games run by the MIT Assassin's Guild ...
