title = "A secure OTP algorithm using a smartphone application",
abstract = "Recently, several authentication protocols are being used in mobile applications. OTP is one of the most powerful authentication methods among them. However, it has some security vulnerabilities, particularly to MITM(Man-in-the-Middle) attack and MITPC/Phone(Man-in-the-PC/Phone) attack. An adversary could know a valid OTP value and be authenticated with this secret information in the presence of those attacks. To solve these problems, we propose a novel OTP algorithm and compare it with existing algorithms. The proposed scheme is secure against MITM attack and MITPC/Phone attack by using a captcha image, IMSI number embedded in SIM card and limiting available time of an attack.",
