    Abstract: Public Key Cryptography (PKC) is recently playing an essential
    role in electronic banking and financial transactions. Elliptic
    Curve Cryptography (ECC) is one of the best public key
    techniques for its small key size and high security and is suitable
    for secure access of smart cards because implementation on
    smart cards is challenging due to memory, bandwidth, and
    computation constraints. In this paper, we proposed a passwordauthenticated
    key agreement scheme based on ECC. Our scheme
    provides more guarantees in security as follows: 1) the
    computation and communication cost is very low; 2) a user can
    freely choose and change his own password; 3) the privacy of
    users can be protected; 4) it generates a session key agreed upon
    by the user and the server; 5) it provides both implicit key and
    explicit key confirmation; and 6) it can prevent the offline
    dictionary attack even if the secret information stored in a smart
    card is compromised. And yet, our scheme is simpler and more
    efficient for smart card authentication
