CRA Quadrennial Papers

Every four years the Computing Research Association, through its subcommittees, publishes a series of white papers called Quadrennial Papers that explore areas and issues around computing research with potential to address national priorities. The white papers attempt to portray a comprehensive picture of the computing research field detailing potential research directions, challenges, and recommendations for policymakers and the computing research community. Our 2020 Quadrennial Papers cover five thematic areas: Core Computer Science, Broad Computing, Socio-Technical Computing, Diversity & Education, and Artificial Intelligence.

Core Computer Science

  • Post Quantum Cryptography: Readiness Challenges and the Approaching Storm

    Authors: Matt Campagna (Amazon), Brian LaMacchia (Microsoft Research), and David Ott (VMware Research)

    Few people are aware that each advancement we make in quantum computing brings us closer to a complete breakdown of our digital security and privacy. As quantum-driven advancements in cryptographic analysis and computing technology are achieved, the cryptographic algorithms that protect our private online information and data is threatened.  This paper identifies issues that need to be addressed before the quantum transition, particularly in identifying a replacement for current cryptography algorithms and ensuring a safe transition of uses.

  • Computing Research Challenges in Next Generation Wireless Networking

    Authors: Elisa Bertino (Purdue University), Daniel Bliss (Arizona State University), Daniel Lopresti (Lehigh University), Larry Peterson (Princeton University), and Henning Schulzrinne (Columbia University)

    Wireless networking has seen explosive growth over the past decade and continues to evolve rapidly. Cellular technology is now progressing from 4G and its potential for broadband speeds to mobile devices, to 5G which will further enhance transmission speeds, cell capacity, and latency through the use of different radio technologies. 6G is already envisioned to employ virtualization across all layers and the pervasive deployment of AI. On the hardware side, new classes of highly flexible application specific processors (ASICs) are being developed, driving further progress. In addition, deep programmability will open up enormous opportunities to manage the complexity and harness the power of the new network infrastructure. This paper explores these key technologies and outlines a research agenda to make them a reality.

Diversity & Education

  • New Pathways for Workforce Diversification

    Authors: Raja Kushalnagar (Gallaudet University), Maria Gini (University of Minnesota), and Patty Lopez (Intel Corporation)

    Diversity enhances computing creativity. This paper recommends computing workforce diversification support through proven strategies of funding Masters programs at institutions committed to diversity, such as Minority Serving Institutions and Special Institutions, or in providing stipend funding for women, black, indigenous and other people of color, or people with disabilities for Masters or undergraduate research programs.

  • Addressing the National Need for Increasing the Domestic PhD Yield in Computer Science

    Authors: Susanne Hambrusch (Purdue University), Lori Pollock (University of Delaware), Ran Libeskind-Hadas (Harvey Mudd College), and Christine Alvarado (University of California, San Diego)

    The continuing demand for PhDs in computer science combined with this instability of international student participation requires bold action to increase the number of domestic students completing a PhD in computer science, especially as the  percentage of domestic PhD students has decreased from 69% in 1985 to 37% in 2018.  This report presents bold ideas on how government, industry, and academia can take action to engage domestic students to enter PhD programs and retain them through graduation.  It focuses on increasing opportunities and funding for undergraduate research, creating new pathways into PhD programs, engaging students from admissions through PhD, and strengthening industry’s role in increasing the number of PhDs in CS.

  • Fostering a Postgraduate Tech Boom

    Authors: Jan Cuny (Northeastern University), Andrea Danyluk (Williams College), and Holly Rushmeier (Yale University)

    In order to maintain its political and economic position in the world, and for that position to benefit its citizens, the United States must build and retain the strongest and most innovative tech talent at all levels. While the CS4All movement is increasing the preparation of current K-12 students for future tech careers, the U.S. cannot wait for future generations to fill the current tech gap. Today’s post-graduate population represents a valuable untapped resource for the country’s workforce needs. This paper outlines opportunities and requirements to fill the tech gap with individuals who bring to the field a diversity of experience and perspectives to fuel innovation, as well as overcome problems of social justice and equity.

Artificial Intelligence

  • Artificial Intelligence at the Edge

    Authors: Sujata Banerjee (VMware Research) and Elisa Bertino (Purdue University)

    Could AI better support societal needs if it were deployed at the edge of the network, close to application end-points, as opposed to in a centralized cloud? This white paper examines those potential uses and identifies requirements and areas of research that need to be explored before implementation of AI systems at the edge can be realized.

  • Artificial Intelligence and Cooperation

    Authors: Elisa Bertino (Purdue University), Finale Doshi-Velez (Harvard University), Maria Gini (University of Minnesota), Daniel Lopresti (Lehigh University), and David Parkes (Harvard University)
