Description
Summary:One Time Password (OTP) is widely used by many online service providers to authenticate the users at the account log-in time. The username and password are fixed; this may be vulnerable for users. To avoid the fake log-in, nowadays service providers are authenticating the users by providing OTP based authentication. The HMAC based OTP (HOTP) and Time based OTP (TOTP) is being used by the online service providers. The combinations used in OTP by the HOTP and TOTP are basically numbers only, due to the minimum resources to generate the OTP. Sometimes numeric OTP had been used by hackers and attackers easily. Request based One Time Passkey (ROTP), created by an OTP is using a combination of numeric value, alphabets in small and capital letters with some permitted special characters. The ROTP Mechanism gives around more than 3 trillion combinations of OTPs. The time to get the validation of ROTP from the users will be fixed same as HOTP and TOTP. Due to more combinations, the hackers and attackers need unexpectable resource to generate and break down the ROTP which were generated and sent to the users for the single time validation purpose. This paper explains about the design and development of Request based One Time Passkey (ROTP) mechanism.
