Science, Technology, and Public Policy

A future where A.I.s interpret, apply, and enforce most laws at societal scale like this will exponentially magnify problems around fairness, transparency, and freedom, warn Jonathon W. Penney and Bruce Schneier.

The cryptocurrency depends on the integrity of the blockchain. But China's censors, the FBI, or powerful corporations could fragment it into oblivion, warn Barath Raghavan and Bruce Schneier.

Over the last two decades, there has been a dramatic increase in the popularity of financial sanctions as an instrument of US foreign policy to address security threats ranging from weapons of mass destruction (WMD) proliferation and terrorism to human rights violations and transnational crime. Washington’s policymakers have prized these tools for their ability to rapidly apply pressure against foreign targets with few perceived repercussions against American business interests. The problem, however, is that Washington is ignoring a growing tension between financial sanctions designed to support economic statecraft (with non-financial goals) and those designed to protect the international financial system. Confusing the two sends mixed signals to adversaries as well as allies and undermines US credibility and commitment to upholding international banking rules and norms. If Washington cannot reconcile these competing processes, it is unlikely that future administrations will enjoy the same foreign policy levers, leaving the United States at a significant disadvantage.

Bruce Schneier elaborates on why the distinction between military and consumer products largely doesn't exist. This means that consumer systems cannot be weakened without also weakening commercial, government, and military systems.

Since September 11, 2001, China has substantially advanced its physical protection system, with a switch in focus from the traditional "guns, gates, guards" approach to an effective mixed approach, combining personnel with modern techniques. Then-Chinese President Hu Jintao emphasized at the 2012 Nuclear Security Summit that, "In the future, China will further take nuclear security measures, make sure the security of its own nuclear materials and facilities, improve the overall nuclear security." This paper examines the specific and detailed physical protection approaches that are currently applied to China's nuclear power plants, and recommends further steps to improve China's existing nuclear security system.
