AB  - In order to solve the limitations of the password-based authentication scheme, various two-factor
authentication schemes for session initiation protocol is studied and regards it as good solution. In 2015, Lu
proposed secure two-factor authenticated key agreement which provide the anonymity and key agreement for
session initiation protocol using elliptic curve cryptography. However, Reddy point out the vulnerability the
Lu scheme and proposed an enhanced anonymous two-factor mutual authentication with key-agreement
scheme for session initiation protocol in 2016 but there are various security problem yet. So, this study analyzes
all phases of Reddy authentication scheme and then shows that their scheme is still vulnerable on off-line
password (and identity) guessing attack a DoS attack, wrong password change phase and session key
disclosure attack.
