Judging from the context in /var/log/messages, it seems likely that the subject message is part of SELinux. Or, maybe it's part of the "RSA [patch#1]". I see references, via Google, to /proc/crypto/keyring/app/adddkey, but in 2.6.7-1.494.2.2, /proc/crypto is the end of the line. This isn't a complaint, not at all. It's just intriguing to see that maybe the kernel will support some kind of cryptology. Yikes! What next? A breath-i-lizer for logging on as root! I'm for that!
