Current Public Key Infrastructures suffer from a scaling problem, and some may have security problems, even given the topological simplification of bridge certification authorities. This paper analyzes the security problems in Bridge Certificate Authorities (BCA) model by using the concept of "impersonation risk," and proposes a new modified BCA model, which enhances its security, but is a bit more complex incertification path building and implementation than the existing one.
