Abstract
One embodiment of the present invention provides a system for managing public keys through a server that stores associations between public keys and email addresses. This system operates by receiving a client public key from a client, and then storing the client public key in a database at the server. The system then allows other clients to lookup the client public key in the database. The system also periodically sends a verification request from the server to the client asking if the client public key remains valid. If an affirmative response to the verification request is not received, the system removes the client public key from the database.
