Abstract— M-banking has emerged as one of the main division of m-commerce. Mobile banking services consists of information inquiry, notifications and alerts, applications and payment transfer. Mobile based application is used for connecting customer handset with bank server for all such services. Current M-banking applications used by banks are facing security challenges for payment transfer banks are using secure payment gateway and other security measures which increases cost and infrastructure for bank but major day-to-day banking applications are inquiries, notifications and alerts. The problem with current banking applications is that they send data directly to customer in plain text form compromising with security.

We present SMS based secure mobile banking which enhances security with minimum cost. In this approach bank hides customer transaction data is secure SMS using AES symmetric cryptographic algorithm and send it customer application supported handset. Customer application decrypts data in secure manner.

Keywords: M-banking, MD5, AES, MPIN
I. INTRODUCTION
M-banking system is one which provides all daily banking operations to customer with one click of his mobile handset with supported application. M-banking system has potential to provide access or delivery of very specific and highly necessary information to customer as given in [2]. Growth in the M-Banking is driven by various facilities like convenience of banking operations, greater reach to consumers and Integration of other m-commerce services with mobile banking. In M-banking there is no place restriction, it is highly penetration coefficient as growth of mobile phones are more than computers, it is fully personalized and private increasing transaction authenticity and is 100% available all the time with users. However, there are several challenges that need to be addressed to completely utilize the benefits of the M-Banking like handset compatibility, security, scalability, reliability. Due to increase in use of mobile handsets for many m-commerce applications, Chances of mobile hacking for financial benefits are heavily increased. Currently mostly all banks in India and outside are sending text SMS directly to the customer handset for basic bank services without any security which can be accessed by any malicious person and can use this information for getting access to customer account. OTA (Over-the-air) mobile data can be hacked in network path from bank to customer mobile handset including MPIN, a password use for user identification in M-banking. Thus there is a need of secure and cost effective solution which can be easily provided on all types of handsets. Our objective is to provide cost effective, secure, fast M-banking solution combining features of cryptography. In this paper we have presented SMS based secure mobile banking with minimum cost using cryptography.

A. Short Message Service (SMS)
SMS is the simplest form of mobile banking. It is largely used for information-based services. SMS has the maximum reach amongst consumers since all the mobile phones support SMS. Short messages are stored and forwarded by SMS centres. These messages have some security issues. B. Unstructured Supplementary Services Delivery (USSD)

USSD is a technology unique to GSM. It is a...
