One-Time Password (OTP) Applet
One-time password (OTP) has become more common in authentication and service access control in new systems. In this sense, Sepid System Company has designed and implemented a specific application for generating OTP with a card. This applet can generate two types of standard OTP:
- TOTP (Time-Based OTP) according to RFC 6238
- HOTP (HMAC-Based OTP) according to RFC 4226
Thus, by using this applet, the user can use his card to generate OTP and, for example, access services that require authentication with a one-time password. The length of OTP, the client password and the confidential information needed for access control (username and password), and the interval of updating the OTP (in the TOTP method) are all flexible and configurable. In addition, the possibility of access control based on matching biometrics on the card (MOC) has also been implemented and can be applied.
