  3. INTRODUCTION • Lee, Hwang and Liao pointed out some security weaknes- sesin Zhu-Ma’s scheme and presented an improved scheme in 2006. • Wu, Lee and Tsaur pointed out that Leeet al.'s scheme doesn’t achieve all security properties in 2008. • Mun et al. pointed out some security weaknesses in Wuet al.'s scheme and proposed the new improved scheme in 2012. • Kim et al. pointed out that Munet al.'sscheme exist security problems of replay attack and man-in-the-middle attack. So they proposed the new improved scheme in 2012.

  4. REVIEW OF MUN’S SCHEME • Registration HA MU Secure Channel Secure Channel

  5. REVIEW OF MUN’S SCHEME • Authentication and establishment of session key FA HA MU

  6. REVIEW OF MUN’S SCHEME • Update session key FA MU 5

  7. WEAKNESS OF MUN’S SCHEME • Replay attack FA HA MU

  8. WEAKNESS OF MUN’S SCHEME • Man-in-the-middle attack FA HA MU SFA ,a’P ,PFA=(SHA||IDFA||NFA) SMF’ ,b’P 7

  9. IMPROVED SCHEME • Registration MU HA Secure Channel

  12. SECURITYANALYSIS • Anonymity FA HA MU 11

  13. SECURITYANALYSIS • Provide perfect forward secrecy MU FA

  14. SECURITYANALYSIS • Prevent replay attack FA HA MU 13

  15. SECURITYANALYSIS • Provide mutual authentication between MU and HA FA HA MU 14

  16. SECURITYANALYSIS • Provide mutual authentication between MU and FA FA HA MU 15

  17. SECURITYANALYSIS • Prevent man-in-the-middle attack FA HA MU

  18. SECURITYANALYSIS

  19. CONCLUSION • In this paper, we discussed the security weaknesses in Mun et al.’s scheme, such as a vulnerability to replay attacks and man-in-the-middle attacks. • The scheme achieves many security problems 1.Anonymity 2.Provides perfect forward secrecy 3.Mutual authentication 4.Prevent replay attacks 5.Prevent Man-in-the-middle attacks.
