Abstract

In representative embodiments keys used in authentication are removed from local systems and stored on a key server system. When keys are needed for authentication, requests are routed to the key server system. In some embodiments, the keys do not leave the key server system and the key server system performs requested operations using the keys. In other embodiments, secure protocols are used to temporarily allow the local system to retrieve and use the key. In this latter situation, keys are not maintained on the local system.
