Abstract
The OTP( ownership transfer protocol) is an important research field of RFID ( Radio Frequency Identification) system due to the rapid development of IOT (Internet of things). This article discusses OTP's application scenario and demonstrates the problem on the security and privacy during tag's ownership transfer process under the supply chain. And based on the existing strand space, an extended secure privacy model is proposed which contains three judge rules, including forward privacy, backward privacy, and key's security. We also use the judge rules to analyze a typical OTP under the proposed Model, and prove that the protocol has both forward and backward privacy problems.
