Our goal is to create novel technological approaches and build real-world systems that:

• Safeguard non-expert users from both technological and social engineering attacks;
• Protect the current and future Internet against Denial-of-Service and routing attacks;
• Design secure sensor networks that are easy to securely set up and maintain; and
• Create a trustworthy computing environment — despite security vulnerabilities in applications and operating systems.

To tackle these challenges, we take a multidisciplinary approach, blending expertise from

• Applied cryptography;
• Public policy analysis;
• Security system design;
  
• Security protocol design; and
• User experience design;
