Abstract
Quite recently [IEEE Commu. Letters, Vol.14, No.1, 2010], Choi et al. proposed a handover authentication scheme using credentials based on chameleon hashing, claiming to provide several security features including Perfect Forward/Backward Secrecy (PFS/PBS). This paper examines the security of the scheme and shows that the scheme still fails to achieve PFS/PBS unlike their claims. Copyright © 2010.
