• Research Shows How Terrorism Affects Our Language and Voting Patterns

    Following the series of terrorist attacks between 2015 and 2017, German twitter users shifted their language towards that of the far right AfD party. Eventually voters rewarded the party at the 2017 election.

  • Quantum Cryptography Applications

    The development of quantum computing means that the use of classic cryptography for secure communications is in danger of becoming obsolete. Quantum cryptography, on the other hand, uses the laws of quantum mechanics to ensure total security. One example of this is quantum key distribution, which enables two parties to secure a message via a random secret key.

  • Cybersecurity Goes Undercover to Protect Electric-Grid Data

    Researchers, inspired by one of the mysteries of human perception, invented a new way to hide sensitive electric grid information from cyberattack: Within a constantly changing color palette.

  • Are We Asking Too Much of Cyber?

    Both cyber enthusiasts and skeptics may be asking too much of cyber. “U.S. cyber strategies should be more explicit about articulating not only the strategic benefits cyberspace offers but also its limitations,” Erica Lonegran and Michael Poznansky write. “More realism about cyberspace may help leaders truly integrate cyber capabilities.”

  • Using Quantum Physics to Secure Wireless Devices

    From access cards and key fobs to Bluetooth speakers, the security of communication between wireless devices is critical to maintaining privacy and preventing theft. Unfortunately, these tools are not foolproof and information on how to hack, clone and bypass these systems is becoming easier to find.

  • CCP’s Increasingly Sophisticated Cyber-enabled Influence Operation

    Last week DOJ announced police officers from China’s Ministry of Public Security (MPS) created thousands of fake online personas on social media sites to target Chinese dissidents through online harassment and threats. The announcement marked the first definitive public attribution to a specific Chinese government agency of covert malign activities on social media. The MPS, however, is one of many party-controlled organizations that analysts have long suspected of conducting covert and coercive operations to influence users on social media.

  • The Key to Securing Legacy Computing Systems

    For a cyber-attack to be successful, one must conduct a sequence of exploits to move from the initial system access, through privilege escalation and lateral motion steps, until reaching the ultimate target. DARPA is pursuing an approach to cyber resilience that would subdivide software systems into smaller, secure compartments that prevent an initial attempt at penetration from becoming a successful attack.

  • “Smart” Tech Coming to a City Near You

    The data-driven smart tech trend extends far beyond our kitchens and living rooms. Will real-time sensors and data offer new solutions to the challenges cities face, or just exacerbate existing inequalities?

  • U.S.-China Tech Competition Expands to AI Regulations

    Competition between the U.S. and China in artificial intelligence has expanded into a race to design and implement comprehensive AI regulations. The efforts to come up with rules to ensure AI’s trustworthiness, safety, and transparency come at a time when governments around the world are exploring the impact of the technology on national security and education.

  • The Liberal Cyber Order

    Grand strategy is a theory of security, a logical narrative about how states employ the instruments of national power to make themselves safe. States may choose from a variety of grand strategies. Joshua Rovner writes that two grand strategies are particularly important to the current U.S. debate: restraint and liberal internationalism. Last month the Biden administration released its National Cybersecurity Strategy, which offers a full display of the foundations of liberal internationalism. This is surprising, since Joe Biden’s approach to national security has always blended liberal ideals with realist restraint.

  • The 2020 Election Saw Fewer People Clicking on Misinformation Websites: Study

    Stanford scholars find a smaller percentage of Americans visited unreliable websites in the run-up to the 2020 U.S. election than in 2016 – which suggests mitigation and education efforts to identify misinformation are working.

  • Banning TikTok Could Weaken Personal Cybersecurity

    TikTok is not be the first app to be scrutinized over the potential exposure of U.S. user data, but it is the first widely used app that the U.S. government has proposed banning over privacy and security concerns. As a cybersecurity researcher, I see potential risks if the U.S. attempts to ban TikTok. The type of risk depends on the type of ban.

  • Anti-Zionism as Antisemitism: How Anti-Zionist Language from the Left and Right Vilifies Jews

    Seven decades after Israel’s founding, some criticism of the country continues to promote age-old antisemitic tropes. Even before Israel was founded, conversations about the Zionist movement and the creation of the State of Israel at times included explicit anti-Jewish animus or espoused ideas historically wielded against Jewish communities. Today, many anti-Zionist activists continue to perpetuate this language.

  • Study Links Hard-Right Social Media with Incidents of Civil Unrest

    An increase in social media activity on “hard-right” platforms — those that purport to represent viewpoints not welcome on “mainstream” platforms — contributes to rightwing civil unrest in the United States, according to a new study. A new Yale-led study finds evidence that social media activity on hard-right platforms contributes to political unrest offline. “The magnitude of the effect we found is modest but two characteristics of social media and civil unrest caution against dismissing it,” said Yale sociologist Daniel Karell.

  • Democracies Must Regulate Digital Agents of Influence

    It would be a mistake to limit the public policy debate to traditional state-on-state espionage or major power rivalry. Such platforms and the advent of the eerily relatable artificial intelligence tool ChatGPT are society-changing technologies that cannot be dismissed as benign or treated as a public good closed to any regulatory or governance process.
