Cryptanalysis Of Chang-Chang-S Ec-Paka Protocol For Wireless Mobile Networks
Hae-Soon Ahn, Eun‐Jun Yoon · Zenodo (CERN European Organization for Nuclear Research) · 2012
With the rapid development of wireless mobile communication, applications for mobile devices must focus on network security. In 2008, Chang-Chang proposed security improvements on the Lu et al.-s elliptic curve authentication key agreement protocol for wireless mobile networks. However, this paper shows that Chang- Chang-s improved protocol is still vulnerable to off-line password guessing attacks unlike their claims.
