Private Information Retrieval (PIR) is a cryptographic primitive that enables a client to retrieve a record from a database hosted by one or more untrusted servers without revealing which record was accessed. It has a wide range of applications, including private web search, private DNS, lightweight cryptocurrency clients, and more. While many existing PIR protocols assume that servers are honest but curious, we explore the scenario where dishonest servers provide incorrect answers to mislead clients into retrieving the wrong results.We begin by presenting a unified classification of protocols that address incorrect server behavior, focusing on the lowest level of resistance—verifiability—which allows the client to detect if the retrieved file is incorrect. Despite this relaxed security notion, verifiability is sufficient for several practical applications, such as private media browsing.Later on, we propose a unified framework for polynomial PIR protocols, encompassing various existing protocols that optimize download rate or total communication cost. We introduce a method to transform a polynomial PIR into a verifiable one without increasing the number of servers. This is achieved by doubling the queries and linking the responses using a secret parameter held by the client.

Muss IT Security in Therapie? Ja, sagt Uta Menges, Doktorandin an der Fakultät für Psychologie der Ruhr-Universität Bochum. Die studierte Familien- und Lebensberaterin forscht zum Thema „IT-Sicherheitslösungen und Risikomanagement in Organisationen“ und schaut dabei mit der therapeutischen Brille auf Beziehungen und Prozesse rund um IT Security. Im Gespräch mit Marcus und Katja erklärt Uta, was dysfunktionale Beziehungen sind und was IT-Security mit Tinder zu tun hat. Uta Menges, Jonas Hielscher, Annalina Buckmann, Annette Kluge, M.

Claire Mathieu is a leading researcher in algorithms design and director of research at Centre national de la recherche scientifique (CNRS) in Paris, France.) Claire has been involved in the 2018 redesign of the college admission procedure in France, where close to a million students apply for more than ten thousand different college programmes. At the root of the procedure is the famous and widely used Stable Marriage method of Gale and Shapley (1962), a result that was recognised with the 2012 Nobel Prize in Economics. Claire explains to us the basic algorithmic ideas, but also the many challenging details that must be addressed when an otherwise clean and well-understood procedure is implemented to tackle a real-world scenario. Many domain-specific peculiarities arise, such as social, cultural, political, administrative, and legal issues, which are themselves often ill-defined and frequently conflicting. The episode was recorded on 20 August 2018, during the European Symposium of Algorithms 2018, hosted by Aalto University in Helsinki, Finland.

This is another episode recorded at the European Symposium 2012 in Wiesbaden. Zsolt Balogh, head of Liferay's Support for the EMEA reason talks about the pain points that led to developing a custom issuetracker and support management system. Enterprise customers know what he's talking about: Liferay is using LESA to handle support issues, fix and escalate them. To follow the visual part of the presentation, please go to the symposium's download page Zsolt starts by laying out why Jira was fine for a single project (and it continues to be in use at issues.liferay.com), but not so much for the way we're supporting the enterprise customers. After introducing the problem space, he's going through implementation timeline, migration, features and requirements, as well as later evolution of the system (naturally, LESA is still being actively developed and extended). Also, there are lots of metrics and how they are helping to improve service or efficiency growing the team. You'll learn how Liferay's support teams were organized internally over the time and where we're heading to. At Liferay, we're not eating our own dogfood, we're rather drinking our own champagne. Where we don't do this now, we're planning to do so very soon. LESA is part of the activity to move a lot of functionality from 3rd party software into Liferay (or to integrate that software into the portal).
Liferay for your ears: Episode 8 is a premiere in this program: Brian Chan, Liferay's founder and Chief Software Architect, is the first that I didn't record in a conversation: Instead this is a recording from Brian's closing keynote at the European Symposium. I had originally planned to record an episode with Brian, but during this keynote he already answered 80% of what I had on my list - and added another 80% that I did not have on my list. So for now I settled with the keynote, well worth listening to The introduction is done by Bryan Cheung, another member of Liferay's founding team and the Chief Executive Officer. As this is the full keynote, I really recommend to listen to it in full, and for that reason don't provide a bullet point list of the topics here. Just this: You'll learn a lot about the setup of the company, the vision, the reason why you want to work with Liferay - the product as well as the company. And why the company will stay with this vision for the foreseeable future. And where the name "Liferay" comes from. And so many more things - Brian is a fast speaker. One of the next episodes will be a follow-up to this episode, as I used the opportunity to sit down with 3/4 of the founder's team, namely all the Brians (This poses a spelling problem: What's the plural of "Brian, Brian and Bryan"? I'll make it "The Brians") You'll find this episode - and make sure that you don't miss any of the future episodes - by subscribing to http://feeds.feedburner.com/RadioLiferay with your favourite podcatcher.

Liferay for your ears: Episode 7 of Radio Liferay is out. I'm speaking with Julio Camarero, Software Engineer in Liferay's spanish office. As a certified Legend he's well known in the forums here, and with regards to this status the highest ranking Liferay-Employee recorded until today. We recorded this episode on very short notice when we met in our german office back in September. We spoke about these topics - and probably more: * User Interface * Accessibility * Localization (Translation Team, Forum, Process) * pootle on http://translate.liferay.com * Initial translation by babelfish * Translation workflow and how to find the context for translations * Visualize all translations and keys on a page (plugin) * The European Symposium (the recording was made prior to the symposium, release is after the event) * Accessibility Guidelines by W3C (WCAG 2.0), Screenreaders * Accessibility through using AlloyUI taglibs and the effect of themes on Accessibility * Guidelines for developent, How to make consistent UIs and how they are made in Liferay (shameless plug: referencing Aaron Delani and Nate Cavanaugh) * Getting from Photoshop to a UI * BugSquad * Different Kinds of Contribution: Just mentioning an issue somewhere does help. If you can help fix the problem, it might help even more, but don't keep any feedback for yourself..)
