  • Bellare, Co-authors Honored for Paper on Encryption vs. Mass Surveillance

    On Tuesday, June 30 in Philadelphia, CSE Prof. Mihir Bellare was among the recipients of the 2015 Privacy-Enhancing Technologies Award. The ceremony was part of the annual Privacy Enhancing Technologies (PET) Symposium. The award honored the three co-authors of a 2014 paper on "Security of Symmetric Encryption Against Mass Surveillance." In their paper, Bellare and his co-authors Phillip Rogaway from UC Davis and Kenneth Paterson at Royal Holloway University of London, described how they were "motivated by revelations concerning population-wide surveillance of encrypted communications" by the National Security Agency, as disclosed in documents released by Edward Snowden and WikiLeaks. [Picturedt: UCSD's Bellare, at left, and Rogaway from UC Davis accepting the PET Award in Philadelphia.] 

    In their paper, Bellare and his colleagues formalized and investigated the resistance of symmetric encryption schemes to mass surveillance, focusing primarily on one type: so-called algorithm-substitution attacks, or ASAs. This involves "big brother" replacing an existing algorithm for encryption with a subverted encryption algorithm. The computer scientists offered both attacks and defenses to ASAs. Among the latter, they showed "how to design symmetric encryption schemes that avoid [ASA] attacks and meet our notion of security."

  • CSE Professor Launches Online Courses in Interaction Design

    Learners around the world, regardless of background, will have the opportunity online to learn how to design great user experiences and what it takes to design technologies that “bring people joy rather than frustration.” The courses were developed by University of California, San Diego Professor Scott Klemmer, who will begin teaching the sequence of seven online courses on “Interaction Design” on the Coursera platform on June 24.

    CSE Prof. Klemmer (pictured) is also a professor of cognitive science in the UC San Diego Division of Social Sciences.The sequence of courses is the first offered by UC San Diego on Coursera since the platform began offering specializations in 2014 for closely related courses – allowing students to master a skill and apply it to a capstone project. Although the courses do not count for credit at UC San Diego, students passing all the courses and getting a Verified Certificate for each can complete a capstone project to earn a Specialization Certificate that demonstrates mastery over the broader skillset.

    “Design is a critical component of the development process in every industry, so we took this opportunity to create a sequence of courses open to everyone, with no particular background required,” said Klemmer, who is also associate director of the Design Lab at UC San Diego. “We are also delighted to be partnering with Instagram co-founder and Director of Engineering Mike Krieger.” Instagram’s Krieger helped Klemmer (his former professor) create the requirements for the final capstone project: to design a creative, end-to-end social user experience using professional interaction design and user-experience (UX) tools. Krieger and Klemmer will judge the projects and provide personalized feedback to the creators of the best designs.

    “Here you get to do an open-ended project where you get to show the world and yourself what you can do with all these design materials,” said Klemmer. “This is a great opportunity to put together a portfolio piece or something you can use to impress your family and friends, or get a job in the design field.”

    The full sequence of courses is geared to students who want to be designers or product managers, but it’s open to anyone. Klemmer covers key elements in the design process. “We start out with need-finding, go through rapid prototyping, make something that is higher fidelity, and test it both in-person and online,” explains Klemmer. “Then students can revise and iterate while polishing the design. Students will be able to experience the whole cycle in the specialization.”  Students learn techniques for brainstorming and generating ideas, how to prototype designs rapidly before implementing them, and how to gather meaningful feedback from users. Students also learn principles of effective visual design, perception and cognition, and how to organize a team’s design process to maximize creative output.

    The seven courses will cover: Human-Centered Design: An Introduction; Design Principles: An Introduction; Social Computing; input and Interaction; User Experience Design; Information Design; and Designing, Running and Analyzing Experiments. The courses are self-paced, with an estimated workload of 10-12 hours per week. The lectures are pre-recorded and they don’t have to be taken in order, although initially only the first two courses are available. Course three is due in July, course four in August, and the remaining courses in the fall.

  • Adjunct CSE Professor Divulges Google's Network Strategy

    This week Google partially lifted the curtain of secrecy surrounding the homegrown network architecture it built over the past decade to handle the massive amount of Internet traffic through the search giant's servers. To divulge the details, Google selected an adjunct CSE professor to go public. Amin Vahdat, who started advising Google while he was still teaching at UC San Diego and leading the university's Center for Networked Systems (CNS), is now a full-time Google Fellow and Technical Lead for Networking at the company, and he remains an adjunct member of the CSE faculty. [Vahdat is pictured below during the 2013 CNS Research Review.]

    Vahdat gave a presentation at the 2015 Open Network Summit on June 17, "revealing for the first time the details of five generations of our in-house network technology," according to Google. While Vahdat was careful about not divulging too many proprietary details, he presented a first look into Google's data center network design and implementation, focusing on the data, control and management plane principles underpinning five generations of our network architecture." Vahdat told the conference that around 2005, the hardware didn't exist that Google required to build a network of the size and speed the company needed. So  instead of buying networking from companies such as Cisco Systems, Google designed its own equipment and had it made to order in Asia and elsewhere. Today, he said, Google designs 100 percent of the networking hardware used inside its data centers. As a result, the company has been able to boost the capacity of a single datacenter network more than 100-fold in 10 years. The current generation of cluster switches, called Jupiter, provide about 40 terabits of bandwidth per second, the equivalent of 40 million home Internet connections. That capability, Vahdat said, is critical to meeting Google's bandwidth and scale demands that are growing exponentially -- doubling approximately every year.

    Timed to coincide with his talk, Vahdat posted an article on the Google Cloud Platform blog. "Our datacenter networks are shared infrastructure," he wrote. "This means that the same networks that power all of Google's internal infrastructure and services also power Google Cloud Platform. We are most excited about opening this capability up to developers across the world so that the next great Internet service or platform can leverage world-class network infrastructure without having to invent it."

    The hallmark of Google's network approach involved moving the complexity out of the hardware and into the software -- so-called software-defined networking -- which allowed the company to build complex networks on top of relatively cheap and abundant microchips. "Taken together, our network control stack has more in common with Google's distributed computing architectures than traditional router-centric Internet protocols," added Vahdat. "Some might even say that we've been deploying and enjoying the benefits of software-defined networking at Google for a decade... these systems come from our early work in datacenter networking." While Vahdat was talking about Google's early work specifically, it's clear that his own early work in CSE and the Center for Networked Systems pointed to the importance of software-defined networking for datacenters -- and he put theory into practice when given the opportunity to create what may be the largest computer network in the world... giving CSE some bragging rights by association. 

  • CSE Student Turn Satellite Images into Policy Analysis

    Recently, over 50 students – 17 of them from CSE – showed up for the day-long Big Pixel Hackathon organized by the Qualcomm Institute's Big Pixel Initiative (BPI) to showcase what can happen when you let students loose on the largest private collection of high-resolution satellite imagery on earth. The three interdisciplinary winning teams each had at least one member from the CSE department, and students tackled subjects ranging from urban slums and natural disasters to human traficking and illegal fishing.

    UC San Diego is one of only two universities offered free access to the entire DigitalGlobe Basemap archive for one year. In addition to nine faculty projects approved so far, the BPI staged a May 23 hackathon that was unlike most hackathons. The teams were not asked to come up with a finished app or clean-cut solution, but rather, to ask big policy questions that might be addressed with satellite imagery that is accurate down to a resolution of half a meter (about 16 inches). Depending on the research question resolved by each team, they were given access to download specific image tiles from the earth database, covering areas including Tijuana and San Diego, French Polynesia, Gujarat and Mumbai in India, oil and gas regions in Texas and Alberta, Canada, Brazil, and so on.

    CSE’s graduate and undergraduate students accounted for the largest number in the hackathon. The next largest contingent after CSE's 17 came from Economics, with eight students. The hackathon distributed $1,500 in cash prizes to the 13 members of the three winning teams.

    In the first category, teams competed to come up with the Best Research Question. The diverse group included CSE sophomore Liz Izhikevich. The team looked at whether satellite images can help predict the impact of small-scale fisheries on the environment. The team came up with a neat computer vision-based solution for detecting hotspots of activity by small fishing boats, often in places where fishing is supposed to be restricted.

    The Most Compelling Visualization/Strategy award went to a five-member team including CSE Master's student Dev Agarwal.  The team set out to track unregistered (i.e., possibly illegitimate) global sea traffic. In principle, this would include the identification of ships carrying migrants (they showed one example of a ship in the Mediterranean crowded with passengers – visible even from a satellite in space).

    Finally, the prize for Most Insightful Discovery went to a team including graduating senior Kevin Hung, a double major in CSE and Mathematics (who is also co-founder of the relatively new Data Science Student Society at UC San Diego). Hung and colleagues asked why some areas recover from natural disaster more quickly than others. The team looked at before-and-after satellite images for differences in color and shape, particularly focusing on the rate at which vegetation grows back. Looking at satellite images of hard-hit Tacloban City before and after Typhoon Haiyan battered the Philippines in November 2013, they came up with a “compute disaster damage” index applied to the before-and-after images. They also looked at other factors that are likely to have an impact on the speed of recovery, ranging from median incomes (which spell faster recovery) to census data.

    On June 17-18, experts from the Big Pixel Initiative including Jessica Block and Ran Goldblatt will visit Digital Globe headquarters in Colorado Springs, CO, to deliver a preliminary report on the UCSD projects that are using Basemap imagery. By next March, Digital Globe will decide whether to continue, expand or disband the university's free access to the Basemap.
