  abstract = {For more than forty years, electronic surveillance law in
		  the United States developed under constitutional and
		  statutory regimes that, given the technology of the day,
		  distinguished content from metadata with ease and
		  certainty. The stability of these legal regimes and the
		  distinctions they facilitated was enabled by the relative
		  stability of these types of data in the traditional
		  telephone network and their obviousness to users. But what
		  happens to these legal frameworks when they confront the
		  Internet? The Internet's complex architecture creates a
		  communication environment where any given individual unit
		  of data may change its status---from content to non-content
		  or visa-versa---as it progresses Internet's layered network
		  stack while traveling from sender to recipient. The
		  unstable, transient status of data traversing the Internet
		  is compounded by the fact that the content or non-content
		  status of any individual unit of data may also depend upon
		  where in the network that unit resides when the question is
		  asked. In this IP-based communications environment, the
		  once-stable legal distinction between content and
		  non-content has steadily eroded to the point of collapse,
		  destroying in its wake any meaningful application of the
		  third party doctrine. Simply put, the world of Katz and
		  Smith and the corresponding statutes that codify the
		  content/non-content distinction and the third party
		  doctrine are no longer capable of accounting for and
		  regulating law enforcement access to data in an IP-mediated
		  communications environment. Building on a deep technical
		  analysis of the Internet architecture, we define new terms,
		  communicative content, architectural content, and
		  architectural metadata, that better reflect the structure
		  of the Internet, and use them to explain why and how we now
		  find ourselves bereft of the once reliable support these
		  foundational legal structures provided. Ultimately, we
		  demonstrate the urgent need for development of new rules
		  and principles capable of regulating law enforcement access
		  to IP-based communications data. },

  abstract = { Twenty years ago, law enforcement organizations lobbied
		  to require data and communication services to engineer
		  their products to guarantee law enforcement access to all
		  data. After lengthy debate and vigorous predictions of
		  enforcement channels ``going dark,'' these attempts to
		  regulate security technologies on the emerging Internet
		  were abandoned. In the intervening years, innovation on the
		  Internet flourished, and law enforcement agencies found new
		  and more effective means of accessing vastly larger
		  quantities of data. Today, there are again calls for
		  regulation to mandate the provision of exceptional access
		  mechanisms. In this article, a group of computer scientists
		  and security experts, many of whom participated in a 1997
		  study of these same topics, has convened to explore the
		  likely effects of imposing extraordinary access mandates.We
		  have found that the damage that could be caused by law
		  enforcement exceptional access requirements would be even
		  greater today than it would have been 20 years ago. In the
		  wake of the growing economic and social cost of the
		  fundamental insecurity of today's Internet environment, any
		  proposals that alter the security dynamics online should be
		  approached with caution. Exceptional access would force
		  Internet system developers to reverse ``forward secrecy''
		  design practices that seek to minimize the impact on user
		  privacy when systems are breached. The complexity of
		  today's Internet environment, with millions of apps and
		  globally connected services, means that new law enforcement
		  requirements are likely to introduce unanticipated, hard to
		  detect security flaws. Beyond these and other technical
		  vulnerabilities, the prospect of globally deployed
		  exceptional access systems raises difficult problems about
		  how such an environment would be governed and how to ensure
		  that such systems would respect human rights and the rule
		  of law. },

  abstract = {In 2004 the increasing number of attacks on U.S. federal
		  civilian agency computer systems caused the government to
		  begin an active effort to protect federal civilian agencies
		  against cyber intrusions . This classified program,
		  EINSTEIN, sought to do real-time, or near real-time,
		  automatic collection, correlation, and analysis of computer
		  intrusion information as a first step in protecting federal
		  civilian agency computer systems . EINSTEIN grew into a
		  series of programs, EINSTEIN, EINSTEIN 2, and EINSTEIN 3,
		  all based on intrusion-detection and intrusion-prevention
		  systems (IDS and IPS). Then there was public discussion of
		  extending the EINSTEIN system to privately held critical
		  infrastructure. \par Extending an EINSTEIN-like program to
		  the private sector raises serious technical and managerial
		  issues. Scale matters, as do the different missions of the
		  private sector and the public one. Expanding EINSTEIN-type
		  technology to critical infrastructure is complicated by the
		  complex legal and regulatory landscapes for such systems.
		  There are simply fundamental differences between
		  communication networks supporting the U.S. federal
		  government and those supporting the private-sector critical
		  infrastructures that create serious difficulties in
		  attempting to extend EINSTEIN-type technologies beyond the
		  federal sector. This paper examines the technology's

  abstract = {For years, legal wiretapping was straightforward: the
		  officer doing the intercept connected a tape recorder or
		  the like to a single pair of wires. By the 1990s, though,
		  the changing structure of telecommunications---there was no
		  longer just ``Ma Bell'' to talk to---and new technologies
		  such as ISDN and cellular telephony made executing a
		  wiretap more complicated for law enforcement. Simple
		  technologies would no longer suffice. In response, Congress
		  passed the Communications Assistance for Law Enforcement
		  Act (CALEA), which mandated a standardized lawful intercept
		  interface on all local phone switches. Technology has
		  continued to progress, and in the face of new forms of
		  communication---Skype, voice chat during multiplayer online
		  games, many forms of instant messaging, etc.---law
		  enforcement is again experiencing problems. The FBI has
		  called this ``Going Dark'': their loss of access to
		  suspects' communication. According to news reports, they
		  want changes to the wiretap laws to require a CALEA-like
		  interface in Internet software. CALEA, though, has its own
		  issues: it is complex software specifically intended to
		  create a security hole---eavesdropping capability---in the
		  already-complex environment of a phone switch. It has
		  unfortunately made wiretapping easier for everyone, not
		  just law enforcement. Congress failed to heed experts'
		  warnings of the danger posed by this mandated
		  vulnerability, but time has proven the experts right. The
		  so-called ``Athens Affair'', where someone used the
		  built-in lawful intercept mechanism to listen to the cell
		  phone calls of high Greek officials, including the Prime
		  Minister, is but one example. In an earlier work, we showed
		  why extending CALEA to the Internet would create very
		  serious problems, including the security problems it has
		  visited on the phone system. In this paper, we explore the
		  viability and implications of an alternative method for
		  addressing law enforcement's need to access communications:
		  legalized hacking of target devices through existing
		  vulnerabilities in end-user software and platforms. The FBI
		  already uses this approach on a small scale; we expect that
		  its use will increase, especially as centralized
		  wiretapping capabilities become less viable. Relying on
		  vulnerabilities and hacking poses a large set of legal and
		  policy questions, some practical and some normative. Among
		  these are: * Will it create disincentives to patching? *
		  Will there be a negative effect on innovation? (Lessons
		  from the so-called ``Crypto Wars'' of the 1990s, and, in
		  particular, the debate over export controls on
		  cryptography, are instructive here.) * Will law
		  enforcement's participation in vulnerabilities purchasing
		  skew the market? * Do local and even state law enforcement
		  agencies have the technical sophistication to develop and
		  use exploits? If not, how should this be handled? A larger
		  FBI role? * Should law enforcement even be participating in
		  a market where many of the sellers and other buyers are
		  themselves criminals? * What happens if these tools are
		  cpatured and repurposed by miscreants? * Should we sanction
		  otherwise-illegal network activity to aid law enforcement?
		  * Is the probability of success from such an approach too
		  low for it to be useful? As we will show, though, these
		  issues are indeed challenging. We regard them, on balance,
		  as preferable to adding more complexity and insecurity to
		  online systems.},
