Query Certificate Managers
A Query Certificate Manager (QCM) is a server used
for the authenticated distribution of sensitive information over an insecure
network. A QCM server acts like a secure, distributed database: it queries
remote QCM servers to answer local queries about distributed data, and
ensures the authenticity of the data by cryptographic means. Moreover,
QCM can accept digitally-signed certificates issued by remote servers.
When such certificates are submitted along with the local query, queries
to the remote servers are short-circuited. The management of queries and
certificates is completely automatic and transparent to the user. Applications
such as directory services, public key distribution, and distributed access
control lists are directly programmable in QCM, and QCM has a formal semantics
and correctness guarantees.
