Methods, systems and computer program products for secure delegation using public key authentication

摘要

Methods, systems and computer program products provide for a middle-tier server to impersonate a client to a plurality of servers. A common nonce associated with each of the plurality of servers is obtained and the common nonce to the client. The common nonce signed by the client is received at the middle-tier server and provided as a signature for transactions from the client to the plurality of servers so as to authenticate the client to the plurality of servers.
