Therefore\, there has been quite an interest in the hardware design and optimization of such multipliers. Th is has led to impressive advancements in this area — such as the use of composite field decomposition techniques\, use of Montgomery multiplicat ion\, among others. \;\n \;\nMy research group has recently begun investigations in the verification of such Galois Field multipliers. Unf ortunately\, the word-length (k) in such multipliers can be very large: typically\, k = 256. Due to such large word-lengths\, verification techn iques based on decision diagrams\, SAT and contemporary SMT solvers are infeasible. We are exploring the use of Computer Algebra techniques\, ma inly Groebner bases theory\, to tackle this problem. In this talk\, we w ill see why Groebner bases techniques look promising\, while at the same time also studying the challanges that have to be overcome.\n\nTags: ga lois\, tech talk\, cryptography\n\nImported from: http://calagator.org/e vents/1250459326 URL:http://www.galois.com/blog/2010/10/07/2007/ SUMMARY:Galois Tech Talk: Application of Computer Algebra Techniques in V erification of Galois Field Multipliers: Potential + Challenges LOCATION:Galois\, Inc: 421 SW 6th Ave. Suite 300\, Portland OR 97204 US SEQUENCE:1 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20120726T210635Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20120822T203000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20120822T183000 DTSTAMP;VALUE=DATE-TIME:20120726T210635Z LAST-MODIFIED;VALUE=DATE-TIME:20120726T210635Z UID:http://calagator.org/events/1250462659 DESCRIPTION:Double Feature! For this chapter meeting\, we have two proto col-oriented talks at PSU. Basic refreshments will be provided. \;\n \;\nKevin P. Dyer presents:What Encryption Leaks and Why Traffic Ana lysis Countermeasures Fail \;\n \;\nAs more applications become we b-based\, an increasing amount of client-server interactions are exposed to our networks and vulnerable to Traffic Analysis (TA) attacks. In one form\, TA attacks \;\nexploit the lengths and timings of packets in a protocol's flow to infer sensitive information about communications. I n the context of encrypted HTTP connections\, such as HTTP over SSH\, th is means \;\nan adversary can determine which website a user is visit ing. In the context of a specific web application\, an adversary can det ermine user input by viewing only a few client-server interactions. \;\n \;\nRecent advances in the application of Machine Learning tools demonstrate that TA attacks are possible despite industry-standard encr yption such as TLS\, SSH or IPSec. What is more\, even if a protocol use s stronger countermeasures\, such as fixed-length per-packet padding\, t his incurs significant overhead but \;\nonly provides limited securit y benefit. These types of security vs. efficiency trade-offs are of imme diate concern to security-aware applications such as Tor\, and performan ce-sensitive application features such as Google Search Autocomplete. 3\;\n \;\nIn this talk\, Kevin will address the state-of-the-art TA a ttacks and proposed countermeasures in the context of network and web ap plication security. Most importantly\, he will discuss open problems in this area and why a general-purpose TA countermeasure remains elusive.&# 13\;\n \;\nTimothy D. Morgan presents:HTTPS\, Cookies\, and Men-in-th e-Middle: Why You Shouldn't Allow Marketing Departments to Design Your S ecurity Protocols \;\n \;\nLogin session management in modern web applications is largely dominated by use of HTTP cookies. However\, HTT P cookies were never designed for secure applications\, which has led to a significant number of protocol security problems. \;\n \;\nIn this talk\, Tim will start with a brief background on why HTTP cookies a re a poorly-conceived mechanism to begin with\, and continue with a disc ussion of how this impacts security. He will describe several lesser-kn own cookie-based session management problems that remain wide spread and allow for session hijacking through a variety of clever attacks. \;\ n \;\nKevin P. Dyer is a PhD student at Portland State University. Hi s research focuses on building protocols that are resistant to Traffic A nalysis attacks. Prior to his academic life\, Kevin worked as an enginee r on various projects in telecommunications security\, web security and network security. Kevin holds an MSc in the Mathematics of Cryptography and Communications from Royal \;\nHolloway\, University of London\, a nd a BS in Computer Science and Mathematics from Santa Clara University. \;\n \;\nTimothy D. Morgan is a consultant at Virtual Security Re search\, LLC (VSR). As an application security specialist and digital f orensics researcher\, Tim has been taking deep technical dives in securi ty for over a decade. Tim resides in Oregon and works at VSR where he h elps to secure his customers' environments through penetration testing\, training\, and forensics investigations.

Dyer presents:P0wning DPI with Format-Transforming E ncryption \;\n \;\nDeep packet inspection (DPI) technologies prov ide much-needed visibility and control of network traffic using port- 3\;\nindependent protocol identification (PIPI)\, where a network flow i s labeled with its application-layer protocol based on packet contents.& #13\;\nIn many cases PIPI can be used for good. As one example\, it allo ws network administrators to elevate priority of time-sensitive (e.g.\,& #13\;\nVoIP) data streams. In other cases PIPI can be used for harm\, na tion-states employ PIPI to block censorship circumvention tools such \;\nas Tor. There are many ways to perform PIPI\, however\, at the core of nearly all modern PIPI systems are regular expressions --- an \;\n expressive tool to compactly specify sets of strings. \;\n \;\n 3\;\nIn this talk\, Kevin reviews the state-of-the-art research on the c apabilities of state-level DPI\, then presents a novel cryptographic \;\nprimitive called format-transforming encryption (FTE.) An FTE scheme \, intuitively\, extends conventional symmetric encryption with the \ ;\nability to transform the ciphertext into a user-defined format using regular expressions. An FTE-based record layer will be presented \;\n that can encrypt arbitrary TCP traffic and coerce modern DPI systems int o misclassifying any data stream as a target protocol (e.g.\, \;\nHTT P\, SMB\, RSTP\, etc.) of the user's choosing. What's more\, this work i s not only theoretical in nature --- an open-source FTE \;\nprototype is publicly available and has had success in subverting modern DPI syst ems\, including the Great Firewall of China. \;\n \;\nPSU is kindl y providing coffee\, tea\, and cookies for us. \;\n \;\nKevin P.

That is\, no-one can gain knowledge about the inputs from the other parties\, except what can be determined from the o utput of the computation. Methods of secure computation include fully ho momorphic encryption (where one party owns the input data and the other party performs the whole computation)\, and secure multiparty computatio n (where multiple parties collaborate in the computation itself). The un derlying methods are still exceedingly costly in time\, space\, and comm unication requirements\, but there are also many other practical problem s to be solved before secure computation can be usable. For programmers\ , the algorithm construction is often nonintuitive\; for compiler writer s\, the machine assumptions are very different from usual\; and for appl ication designers\, the application information flow has to match the se curity architecture.

Clearly\, no matter how strong of an encryption you use\, access pa ttern is revealed: Cloud Server can simply track where on the hard drive you read/write from – clearly encryption does not hide that information . One naive solution to prevent revealing access pattern to the Server i s to simply read all your data back from the Server and re-write your en tire data back to Server in its entirety for each read/write. This works \, but it is clearly impractical. Oblivious Random Access Memory (ORAM) is an algorithm that allows you to completely hide arbitrary access patt ern in an efficient manner. In this talk\, I will describe Oblivious RAM from the ground up\, starting from my own Ph.D. thesis work on this top ic (STOC 1990\, MIT Ph.D. 1992) which showed the first efficient ORAM. T he Journal Version of this work gained over 450 references according to Google Scholar [Ostrovsky-Goldreich JACM 1996] and ORAM became an import ant area of research in Cryptography in the last 5 years. I will describ e surprising connections of ORAM to (1) tamper-proof embedded systems\, (2) Software Protection (3) Secure Multi-Party and Secure Two Party Comp utation as well as (4) ways to securely compile programs with loops\, “g oto” statements\, recursion\, etc. into Garbled programs without “unroll ing” the execution path\, yet not revealing anything about the execution path. I will also compare and contrast ORAM to Single-Server Private In formation Retrieval (Single-server PIR)\, which I co-invented with Kushi levitz in 1997\, and explain important differences of these two models. The talk will be self-contained and accessible to the general audience.& #13\;\n \;\nSpeaker bio: Rafail Ostrovsky is a Professor of Computer Science and Professor of Mathematics at UCLA and co-founder of Stealth S oftware Technologies\, Inc.

(There is no need to pre-register for the talk.) \;\n \;\n### Abstract ###&# 13\;\n \;\nEasyCrypt is a computer-assisted framework for proving the security of cryptographic constructions. However\, there is a significa nt gap between security proofs done in the usual provable security style and cryptographic implementations used in practice\; as a consequence\, real-world cryptography is sometimes considered as “one of the many ong oing disaster areas in security. We have recently extended EasyCrypt wit h support for reasoning about C implementations\, and exploited the Comp Cert verified compiler to carry the security proof to executable code. Moreover\, we have developed verified type-based information flow analys es on assembly code to ensure that executable code is protected against cache-based side-channel attacks. \;\n \;\n### Bio ### \;\n \;\nGilles Barthe received a Ph.D. in Mathematics from the University of Manchester\, UK\, in 1993\, and an Habilitation à diriger les recherche s in Computer Science from the University of Nice\, France\, in 2004.

They definitely input a String and output gibberish that looks like encrypted text\, but they are often incorrect. Crypto is tric ky: it’s hard to tell that the gibberish that’s being printed is not goo d crypto\, and it’s hard to tell that the code example you picked up fro m Stack Overflow has serious flaws. \;\n \;\nThe problem here is t hat sites like Google and Stack Overflow rank results based on popularit y\, but the correctness of crypto isn’t something we can vote about. It’ s not a popularity contest. To use it correctly\, you have to understand the properties of the algorithm and the security goals of your code. Ma ybe the bad crypto someone pasted up on the Internet was acceptable for their needs\, but there’s a good chance it’s completely unacceptable for yours. \;\n \;\nIn this talk\, we’ll discuss the use of a very co mmon crypto algorithm\, AES\, and show how code examples on the Internet usually make serious mistakes in how they use AES libraries. What are t he consequences of these mistakes and what are more reasonable defaults. We’ll also talk a bit about our simple Android library that tries to do AES right. \;\n \;\nMore information on the Tozny blog: http://to zny.com/blog/encrypting-strings-in-android-lets-make-better-mistakes/ 3\;\n \;\nbio: \;\nIsaac is a security researcher at Galois where he has lead authentication and collaboration projects for the DoD and IC .
