In one example in accordance with the present disclosure, a method may comprise establishing, by a boot environment, a secure connection on a special port. An authentication key for the secure connection is preloaded into the boot environment. The method may comprise verifying, by the admin node, that the new node is marked for installation and transmitting, by the admin node, a secure key to the new node over the secure connection. The method may comprise requesting, by the boot environment, a secure bundle from the admin node, the secure bundle corresponding to the new node. The method may comprise decrypting, by the boot environment, the secure bundle using the secure key and requesting, by the boot environment, an installation image for the new node.
