With these types of electronics, the system cannot successfully work in the authentication phase while the registration process is implemented based on a computer keyboard.
However, some devices have no standard desktop keyboard such as personal digital assistants and mobile phones.

Users are verified by checking the validity of the password and typing characteristics. Purpose – In keystroke-based authentication systems, an input device to enter a password is needed. To enhance the security of the S-3PAKE protocol, we suggest a countermeasure against our impersonation-of-initiator attack, impersonation-of-responder attack, and man-in-the-middle attack.
In this paper, we first briefly review the S-3PAKE protocol, and then demonstrate its weaknesses by using traditional informal description and formal description, respectively. However, we find that the S-3PAKE protocol is still vulnerable to an impersonation-of-initiator attack, an impersonation-of-responder attack, and a man-in-the-middle attack. They claimed that their protocol is superior to similar protocols with respect to security and efficiency. Recently, Lu and Cao proposed a simple three-party password-based authenticated key exchange (S-3PAKE) protocol based on the CCDH assumption. demonstrated that Wen et al.’s protocol cannot resist a man-in-the-middle attack, and then interpreted their attack in the context of the formal proof model. proposed a three-party password-based authenticated key exchange protocol using Weil pairing and showed that their protocol is provably secure. Compared with Lee-Lee's protocol, the proposed protocol is very useful in password-based Internet and wire/wireless communication environments to access remote information systems since it provides security, reliability and efficiency. The current paper, however, demonstrates that Lee-Lee's password based authenticated key agreement protocol is still vulnerable to off-line password guessing attacks, and then proposes an improvement of the protocol in order to overcome such security attacks. Lee et al.'s password based authenticated key agreement protocol is vulnerable to a man-in-the-middle attack, and then proposed an improvement to overcome the attack. Recently, Lee and Lee pointed out that N. Password based authenticated key agreement protocols, however, are vulnerable to password guessing attacks since users usually choose easy-to-remember passwords. Password based authenticated key agreement protocols have been the most widely used methods for user authentication, since it allows people to choose and remem-ber their own passwords without any assistant device.
