Modeling and analysis of RFID authentication protocols for supply chain management

Abstract

A secure interconnection of objects through RFID technology extends the range of information availability. Security in this integration is achievable through proper identification, authentication, grouping / yoking, distance bounding, and tag and ownership transfer protocols. This work analyzes the computational and communicational cost of group and authentication protocols. Further, these protocols are modeled and analyzed using alloy model. Results show that a network of 255 nodes can be constructed with delays of 9.6 msec and 7.6 msec using peer to peer and centralized connectivity respectively.
