Abstract
Bridge CA's allow PKI systems at a variety of organizations to interoperate. In the last several months, two important bridges have been tested: A Federal Bridge, which links PKI systems of several government agencies, and a Higher Education Bridge (HEBCA), which currently links three educational institutions. This session will discuss both of these bridges, and will describe a pilot project in which researchers and administrators from the three HEBCA schools submitted digitally-signed grant applications to the NIH.
