A Dynamic Mutual RFID Authentication Model Preventing Unauthorized Third Party Access

Abstract

RFID implementations leverage competitive business advantages in processing, tracking and tracing of fast-moving goods. Most of them suffer from security threats and the resulting privacy risks as RFID technology was not designed for exchange of sensible data. Emerging global RFID-aided supply chains require open interfaces for data exchange of confidential business data between business partners. We present a mutual authentication model based on one-time passwords preventing tag access by unauthorized third parties. Compared to models using complex on-tag encryption methods our implementation focuses on reducing tag-manufacturing costs while increasing customers’ acceptance for RFID technology.
