Cloud-Based Lightweight RFID Mutual Authentication Protocol

摘要

Radio Frequency Identification (RFID) makes it a supporting technology for the Internet of things (IoT). While RFID has been widely used and developed rapidly, its security and privacy issues cannot be ignored. With the development of cloud computing, cloud based RFID system has become a new solution. Protecting the security of RFID system in cloud environment is particularly important. Not verifying the tag or reader when reading message will have serious consequences, which may suffer many secure issues, such as intercept, modifying, replaying, DoS and synchronization. This paper puts forward an efficient and reliable RFID security authentication scheme in cloud environment. The protocol combines the logic encryption operation with timestamp, which can resist DoS attacks and anti-synchronization attacks. The proposed protocol not only can well solve the RFID security and privacy issues, but also can use the powerful cloud computing capabilities to process data.
