This document proposes using a one-time password system with a GSM modem for ATM authentication. A microcontroller like the Atmega-16 would generate an OTP on the GSM modem when a user enters their phone number at the ATM keypad. The OTP would be sent as an SMS to the user's phone, who must then enter it at the ATM within a set time to authenticate the transaction. This system avoids the vulnerabilities of static passwords while allowing authentication via a user's mobile phone.

GSM BASED AUTHENTICATION USING ONE TIME PASSWORD FOR ATM MACHINE ABSTRACT A one-time password (OTP) is a password that is valid for only one login session or transaction. OTPs avoid a number of shortcomings that are associated with traditional (static) passwords. The most important shortcoming that is addressed by OTPs is that, in contrast to static passwords, they are not vulnerable to replay attacks. This means that a potential intruder who manages to record an OTP that was already used to log into a service or to conduct a transaction will not be able to abuse it, since it will be no longer valid. On the downside, OTPs are difficult for human beings to memorize. Therefore they require additional technology to work. BLOCK DIAGRAM Atmega-16 MICROCONTROLLER GSM MODEM
