2. Introduction Scenario Internet
Intercept: Delete, modify, fabricate ; corrupt: clients

3. Motivations ? Pre-share key ? Pre-share key Miyoung-Rhee (2011)
Vulnerable to off-line password guessing
attack and user impersonation attack
Does not provide user with anonymity
This proposed scheme
Proposed a scheme to achieve:
User anonymity
Resist most known attacks
Intercept: Delete, modify, fabricate ; corrupt: clients
? Pre-share key

14. Conclusions Secure against various known attacks
Use anonymity
Secure against various known attacks
But high computational cost
Automated Validation of Internet Security Protocols and Applications.

15. Comments Large number of rounds Long delays
NCC should verify the session key
Offline identity guessing attack
AAKE:
Verify
End-to-End communication?
