Susan Landau
Susan Landau is a Distinguished Engineer at Sun Microsystems
Laboratories, where she concentrates on the interplay between security
and public policy. She is currently working on surveillance issues.
Her earlier activities included digital rights management, where she
helped establish Sun's stance on DRM, and work on cryptography and
export control. Before joining Sun,
Landau was a faculty member at the University of Massachusetts and
Wesleyan University, and held visiting positions at Yale, Cornell, and
the Mathematical Sciences Research Institute at Berkeley. She also
spent many summers teaching at
the Hampshire College Summer Studies
in Mathematics, a program for high-ability high school students
(cf. Supporting
a National Treasure).
In recent years Landau has focused on the security risks of
embedding surveillance within communications infrastructures. She has
participated in several industry reports on the issue, and has written
articles for the Washington Post, IEEE Security and Privacy, the
Journal of Telecommunications and High Technology Law, and the
Communications of the ACM. Her earlier focus was on cryptographic
policy issues. Landau and Whitfield Diffie have
written Privacy
on the Line: The Politics of Wiretapping and Encryption, which won
the 1998 Donald McGannon Communication Policy Research Award, and the
1999 IEEE-USA Award for Distinguished Literary Contributions
Furthering Public Understanding of the Profession (an updated and
expanded edition was published in spring 2007.) Landau is also primary
author of the 1994 Association for Computing Machinery report ``Codes,
Keys, and Conflicts: Issues in US Crypto Policy.'' With Sun CTO Greg
Papadopoulos, Landau helped establish Sun's principles on
digital-rights management, including ``All creators are users, and
many users are creators,'' and ``Respect for users' privacy is
essential.'' Sun's DRM project, DReaM, provides support for fair use,
the only DRM system to do so. Prior to her work in policy, Landau did
research in symbolic computation and algebraic algorithms, discovering
several polynomial-time algorithms for problems that previously only
had exponential-time solutions.
Landau
started researcHers,
a mailing list for women computer science researchers in academia,
industry and government labs and with Elaine Weyuker, she created
the
ACM-W Athena Lectureship, an award celebrating outstanding women
researchers. In 2008 Landau co-chaired
the MIT
Celebration of Women in Math meeting. She is a member of
the Computing Research
Association Committee on the Status of Women in Computing Research
(CRAW), and serves on the advisory board of ACM-W.
Landau is the recipient of
the
2008 Women of Vision Social Impact Award, a Fellow of
the American Association for the
Advancement of Science and
an ACM Distinguished Engineer. She
served for six years on the National Institute of Standards and
Technology's Information
Security and Privacy Advisory Board, and has been a member of the
Association for Computing Machinery's Advisory Committee on Privacy
and Security and ACM's Committee on Law and Computing Technology as
well as an associate editor of
the Notices of the American
Mathematical Society. She has appeared on NPR several times, and
has had articles published in the ``Boston Globe,'' ``Chicago
Tribune,'' ``Christian Science Monitor,'' ``Scientific American,''
``Washington Post,'' as well as in numerous scientific journals.
Landau received her PhD from MIT (1983), her MS from Cornell (1979),
and her BA from Princeton (1976).
