Abstract: On-line ARECA’S ability to protect its private key enables it to sign certificates or revoke certificates securely, yet to be a secure on-line CA, its repository should also be protected. ARECA’S repository comprises several replicated servers and is designed into a Dissemination Quorum System, which can mask the benign failure or Byzantine (even malign) failure of the servers. ARECA’S repository is able to provide correct service even when at most f servers of the n (n>3f) servers fail.

Key words: Intrusion tolerant, Byzantine Quorum Systems, CA, Repository
