Unlinkability. In our proposed scheme, the real identities or related information of all participants are not sent in plaintext over the insecure network because each transmitted message contains timestamps, random values and one-way hash function values. An outside adversary A cannot determine whether two or more authentication messages come from the same participant. Therefore, the transmitted messages cannot be linked by the adversary.
