Online applications using strong authentication with OTP grid cardsBayalagmaa Davaanyam
This document discusses using grid cards with one-time passwords for strong authentication in online applications in Mongolia. It proposes a system where users are prompted with random grid card cell coordinates and must enter the corresponding password to authenticate. Passwords are created from the grid card contents using a one-time password algorithm. This provides two-factor authentication by combining something the user possesses (the grid card) with dynamically generated passwords. The document analyzes security aspects and compares this approach to other authentication methods used in Mongolian banking, concluding that grid cards can help improve online security in a cost-effective manner.
This document discusses using one-time password (OTP) grid cards for strong authentication in online applications in Mongolia. It proposes a system where OTPs are generated from grid cards containing numbers and letters. When logging in, a user must provide their password and the contents of a randomly selected cell from their unique grid card. Adding salt passwords and generating challenges from least-used cells increases security by preventing prediction of responses. The system aims to improve online banking security in Mongolia by providing multi-factor authentication without specialized hardware tokens.
