A path is secured from one node to another node of the computing environment. The one node obtains a first encryption key and one or more first parameters for transmission of data, and a second encryption key and one or more second parameters for reception of data. A shared key is obtained by the one node from a key server, and the shared key is used to encrypt a message. The encrypted message includes the first encryption key, the one or more first parameters, the second encryption key and the one or more second parameters. The encrypted message and an identifier of the shared key is sent from the one node to the other node, and a response message is received by the one node. The response message at least provides an indication that the other node received the encrypted message and obtained the shared key.
