  1. RFID Paper presentation The Security of EPC Gen2 Compliant RFID Protocols Source ： Applied Cryptography and Network Security, VOL. 5037, 2008, pp. 490-506 Authors :Mike Burmester,Breno De Medeiros • A Practical Approach for Enhancing Security of EPC global RFID Gen2 Tag • Source ： Future Generation Communication and Networking, VOL. 1, NO. 5, Dec 2007, pp.436-441 • Authors :Jaemin Park Speaker : Chia- Hung Chang Date : 2012-11-25

  2. Outline • Introduction • RelateWork • Proposed Scheme • Security analysis • Conclusion& Future Work

  3. Introduction(1/2) Tag Reader Sever (1)Request (2)Response (2)Response (3)Authenticate (4) Forward phase (4) Forward phase

  4. Introduction(2/2) Tag in C1Gen2 only can use • Pseudo-random number generator(PRNG) - 16 bits • Cyclic Redundancy Code(CRC) - 16 bits

  5. Protocol notations

  6. RelateWork- Duc-Park-Lee-Kim RFID Protocol [10](1/2)

  7. RelateWork- Duc-Park-Lee-Kim RFID Protocol [10] (2/2)

  8. RelateWork- Chien-Chen RFID Protocol [9](1/2)

  9. RelateWork- Chien-Chen RFID Protocol [9] (2/2)

  10. Proposed Scheme1- Scheme design • 3Trivial protocol • TRAP 0 - RNG • TRAP 1 - Modify RNG • TRAP 2 - Anonymity (TRAP 3  Class2 Gen2)

  11. Proposed Scheme1- TRAP 0

  12. Proposed Scheme1- TRAP 1(1/2) • Pseudo-random number generator(PRNG) • Concerns exhaustive-key attacks • Concerns related-key attacks • Pseudo-random function (PRF)

  13. Proposed Scheme1- TRAP 1(2/2)

  14. Proposed Scheme1- TRAP 2*

  15. A Practical Approach for Enhancing Security of EPC global RFID Gen2 Tag Source ： Future Generation Communication and Networking, VOL. 1, NO. 5, Dec 2007, pp.436-441 Authors :JaeminPark

  16. Proposed Scheme2-Setting

  17. Proposed Scheme2-Authenticate (1/2)

  18. Proposed Scheme2-Authenticate (2/2)

  19. Comparison- A Practical Approach for Enhancing Security of EPC global RFID Gen2 Tag

  20. Conclusions • Two papers can both follow C1Gen2 • Both can defense replay attack and have anonymity
