Abstract
Authentication is performed on a plurality of links of a computing environment. One node requests generation of a shared key by a key server coupled to the one node. The one node obtains the shared key and an identifier of the shared key and sends the identifier from the one node to another node. A message encrypted with the shared key is sent from the one node to the other node via one link of the plurality of links. The one node receives via the one link an indication that the other node decrypted the encrypted message using the shared key obtained by the other node. The sending the encrypted message and the receiving the indication that the other node decrypted the encrypted message are repeated on one or more other links of the plurality of links using the shared key previously obtained.
