BITS Networked Systems Laboratory
The BITS laboratory does a variety of research in Networked Systems. Our work revolves around real-world applications, such as open wireless Internet access, transit navigation, and traffic management.

Featured Research Projects

Cloudsweeper

Cloudsweeper allows users to audit, encrypt, and redact sensitive information within cloud storage accounts. This project helps us better understand the role of cleartext password emailing, the underground value of stolen accounts, and new ways to improve the security of sensitive, globally acceissible information.
