    initiating a second message conversation between the authenticator and the supplicant, wherein the second message conversation is cryptographically protected using the same security context that was created in the first message conversation;

    providing a security credential to the supplicant in the second message conversation;

    concluding the second message conversation and the first message conversation;

    wherein the first message conversation and the second message conversation are for granting initial network access.
