Paper Title
OTP For Mission Critical Applications

Abstract
Mission critical information travels through the Internet, requires support for security properties such as authentication, authorization, data confidentiality. In banking transaction password conjecture and wiretapping that can happen when using the same password have been solved by one time password (OTP). OTP mechanism is exposed to various attacks and is vulnerable in matters of confidentiality and security depending on the mechanism. This paper proposes a new scheme of OTP that has enhanced security using specific amount transaction to prevent modification in the transaction details and offset any attacks by integrating MAC (medium access control) address of the legitimate user device. Comparison and analysis of existing OTP mechanism has been made and results reported. Keywords— One Time Password, Authentication, Authorization, Access Control, Single and Multiple Factor Authentication.
