Abstract: According to the insufficiency of the traditional Internet Of Things (IOT) on privacy protection, an improved enquiry system of IOT-Trusted Anonymous Object Naming Service (TA-ONS) was proposed with trusted computing technology, adding anonymous certification to the traditional ONS enquiry system of IOT, authenticating the identities and platform creditability of local ONS servers (L-ONS), and giving temporary certificates to validated L-ONS. Within the authentication period, L-ONS could apply for more than once enquiry services from TA-ONS with the certificate. TA-ONS only provided enquiry services to those authorized and trusted L-ONS, prevented the illegal L-ONS to enquire information of things. The universally composable security model was used as safety check. The analysis shows that the new enquiry system model of IOT is safe, anonymous, trusted and efficient.
