2. Introduction (1/1)

3. Proposed scheme (1/7)
Five phases: - the setup phase - the user registration phase - the server registration phase - the mutual authentication phase - the password change phase

4. Proposed scheme (2/7)
the setup phase

5. Proposed scheme (3/7)
the user registration phase

6. Proposed scheme (4/7)
the server registration phase

7. Proposed scheme (5/7)
the mutual authentication phase

8. Proposed scheme (6/7)
the mutual authentication phase

9. Proposed scheme (7/7)
the password change phase

10. Security analysis SR − 1: single registration
SR − 2: mutual authentication
SR − 3: user anonymity
SR − 4: un-traceability
SR − 5: session key agreement
SR − 6: perfect forward secrecy
SR − 7: two-factor security
SR − 8: not using the verifier table
SR − 9: no on-line registration center SR − 10: resistance of various attacks

11. Performance
Computation cost comparisons
Communication cost comparison

12. Conclusions
The security analysis shows that the proposed protocol is provably secure in the random oracle model
This scheme satisfies the security requirements in the mobile system with multi-server architectures.
The performance analysis results show that the proposed protocol has lower communication and computation costs.
