Abstract
A path for a node of a computing environment is secured. The securing includes obtaining, by the node, a message that includes an identifier of a shared key and an encrypted message, the encrypted message including a first encryption key, a second encryption key, one or more first parameters and one or more second parameters. The node obtains the shared key from a key server and uses it to decrypt the encrypted message to obtain the first encryption key, the second encryption key, the one or more first parameters and the one or more second parameters. A second security parameters index, to be associated with the second encryption key and the one or more second parameters, is obtained. The node sends a response message to another node, the response message including the second security parameters index.
