  • Automatic Program Repair Using Genetic Programming
    Automatic Program Repair Using Genetic Programming A Dissertation Presented to the Faculty of the School of Engineering and Applied Science University of Virginia In Partial Fulfillment of the requirements for the Degree Doctor of Philosophy (Computer Science) by Claire Le Goues May 2013 c 2013 Claire Le Goues Abstract Software quality is an urgent problem. There are so many bugs in industrial program source code that mature software projects are known to ship with both known and unknown bugs [1], and the number of outstanding defects typically exceeds the resources available to address them [2]. This has become a pressing economic problem whose costs in the United States can be measured in the billions of dollars annually [3]. A dominant reason that software defects are so expensive is that fixing them remains a manual process. The process of identifying, triaging, reproducing, and localizing a particular bug, coupled with the task of understanding the underlying error, identifying a set of code changes that address it correctly, and then verifying those changes, costs both time [4] and money. Moreover, the cost of repairing a defect can increase by orders of magnitude as development progresses [5]. As a result, many defects, including critical security defects [6], remain unaddressed for long periods of time [7]. Moreover, humans are error-prone, and many human fixes are imperfect, in that they are either incorrect or lead to crashes, hangs, corruption, or security problems [8]. As a result, defect repair has become a major component of software maintenance, which in turn consumes up to 90% of the total lifecycle cost of a given piece of software [9].

  • Register with Tarsnap Installation
    For the past year I've been working on Tarsnap GUI, an open source cross-platform frontend for the Tarsnap backup service. Tarsnap is an online, fully encrypted, deduplicated, online backup solution, that's been around for close to 10 years now (unlike other online backup offerings with a lifespan smaller than 5 years). Starting with day one, full source code for the client tools was available for review and to establish trust. A bug bounty program is available and any kind of reporting is taken seriously, promptly responded and adequately rewarded by the creator and principal developer of Tarsnap, Colin Percival. Tarsnap uses a prepaid model, you add credit to your account and you'll only pay for what you use and nothing more, no annual or monthly subscriptions. For the moment, the price per MB (SI notation) of storage (used monthly) and MB transferred is 250 picodollars each. The backend infrastructure is powered by AWS. Tarsnap was originally offered as a command-line suite of tools, in true allegiance to the Unix philosophy, very similar to the tar utility, for maximum flexibility and control over your backup routines and of great relevance for the server world. Die-hard Unix users and admins see no distinction between server administration and personal workstation and thus nothing is stopping you from backing up your personal machines and workstations the same way you would a networked server. Tarsnap GUI comes to the rescue here in filling whatever gap might be between the server and desktop workflows and for the people that like to keep real work inside the Terminal and all else contained in easy to use, slim, yet robust GUIs.

Esto impide el uso de estas herramientas a entidades que necesiten que sus datos no salgan de su entorno, por lo que el objetivo de este Proyecto de Fin de Carrera es el dise~no y desarrollo de un sistema similar a estos otros productos. Se analizan las caracter´ısticasde los competidores, y se dise~naun programa que incluye en el n´ucleolas caracter´ısticasb´asicasy sea capaz de incluir to- das las caracter´ısticasadicionales mediante el uso de extensiones o plugins. Es precisamente esta extensibilidad la que caracteriza el sistema, permitiendo que un mismo producto pueda adaptarse a las necesidades de multitud de clientes, que pueden precisar, por ejemplo, de distintos sistemas de autenticaci´on(para integrar el sistema en la arquitectura existente) o utilizar la infraestructura para sincronizar m´asque ficheros.

  • A Model to Manage Shared Mutable Data in a Distributed Environment
    THE SEA OF STUFF: A MODEL TO MANAGE SHARED MUTABLE DATA IN A DISTRIBUTED ENVIRONMENT Simone Ivan Conte A Thesis Submitted for the Degree of PhD at the University of St Andrews 2018 Full metadata for this thesis is available in St Andrews Research Repository at: http://research-repository.st-andrews.ac.uk/ Please use this identifier to cite or link to this thesis: http://hdl.handle.net/10023/16827 This item is protected by original copyright This item is licensed under a Creative Commons Licence https://creativecommons.org/licenses/by-nc-nd/4.0/ The Sea of Stuff: a Model to Manage Shared Mutable Data in a Distributed Environment Simone Ivan Conte This thesis is submitted in partial fulfilment for the degree of Doctor of Philosophy (PhD) at the University of St Andrews August 2018 ii Abstract Managing data is one of the main challenges in distributed systems and computer science in general. Data is created, shared, and managed across heterogeneous distributed systems of users, services, applications, and devices without a clear and comprehensive data model. This technological fragmentation and lack of a common data model result in a poor understanding of what data is, how it evolves over time, how it should be managed in a distributed system, and how it should be protected and shared. From a user perspective, for example, backing up data over multiple devices is a hard and error-prone process, or synchronising data with a cloud storage service can result in conflicts and unpredictable behaviours. This thesis identifies three challenges in data management: (1) how to extend the current data abstractions so that content, for example, is accessible irrespective of its location, versionable, and easy to distribute; (2) how to enable transparent data storage relative to locations, users, applications, and services; and (3) how to allow data owners to protect data against malicious users and automatically control content over a distributed system.

  • The PGP Problem Latacora
    13/06/2020 Latacora - The PGP Problem Latacora About Archive The PGP Problem Jul 16, 2019 Cryptography engineers have been tearing their hair out over PGP’s deÙciencies for (literally) decades. When other kinds of engineers get wind of this, they’re shocked. PGP is bad? Why do people keep telling me to use PGP? The answer is that they shouldn’t be telling you that, because PGP is bad and needs to go away. There are, as you’re about to see, lots of problems with PGP. Fortunately, if you’re not morbidly curious, there’s a simple meta-problem with it: it was designed in the 1990s, before serious modern cryptography. No competent crypto engineer would design a system that looked like PGP today, nor tolerate most of its defects in any other design. Serious cryptographers have largely given up on PGP and don’t spend much time publishing on it anymore (with a notable exception). Well-understood problems in PGP have gone unaddressed for over a decade because of this. Two quick notes: Ùrst, we wrote this for engineers, not lawyers and activists. Second: “PGP” can mean a bunch of things, from the OpenPGP standard to its reference implementation in GnuPG. We use the term “PGP” to cover all of these things. The Problems Absurd Complexity For reasons none of us here in the future understand, PGP has a packet-based structure. A PGP message (in a “.asc” Ùle) is an archive of typed packets. There are at least 8 different ways of encoding the length of a packet, depending on whether you’re using “new” or “old” format packets.

  • A Worldwide Survey of Encryption Products
    A Worldwide Survey of Encryption Products Bruce Schneier Kathleen Seidel Saranya Vijayakumar Berkman Center for Internet Independent Researcher Harvard College and Society [email protected] [email protected] Harvard University [email protected] February 11, 2016 Version 1.0 Introduction Data security is a worldwide problem, and there is a wide world of encryption solutions available to help solve this problem. Most of these products are developed and sold by for-profit entities, although some are created as free open-source projects. They are available, either for sale or free download, all over the world. In 1999, a group of researchers from George Washington University attempted to survey the worldwide market for encryption products [HB+99]. The impetus for their survey was the ongoing debate about US encryption export controls. By collecting information about 805 hardware and software encryption products from 35 countries outside the US, the researchers showed that restricting the export of encryption products did nothing to reduce their availability around the world, while at the same time putting US companies at a competitive disadvantage in the information security market. Seventeen years later, we have tried to replicate this survey. Findings We collected information on as many encryption products as we could find anywhere in the world. This is a summary of our findings: We have identified 865 hardware or software products incorporating encryption from 55 different countries. This includes 546 encryption products from outside the US, representing two-thirds of the total. Table 1 summarizes the number of products from each country. The most common non-US country for encryption products is Germany, with 112 products.
