Step 9: The final step is to authenticate the device Di. Mutual authentication can be established by checking that the HD and Di have obtained the same shared secret. This is because the device Di has sent the HD the signed certificate containing a copy of its public key and the unique HD is the only entity with access to the secret conjugate material and T -values enabling it to produce the correct response. Methods for doing this, such as using a hash to create a validation value or using a nonce and Message Authentication Code (MAC) in a challenge/response protocol, are well known, so we do not reproduce them here.

the certificate. If the certificate is not valid the protocol terminates. This is the method we propose in Step 1 of the Ironwood Protocol. Next, assume certificates are not being used in the protocol. Then the HD must check that
