Design Limitations Characteristicsand Analysis of Secure Mobile Transaction and Protocols

Today, new technologies that allow cellular (mobile) phones and other handheld devices to access the Internet have made wireless business transactions possible. This phenomenon is known as mobile commerce or M-Commerce. What must be done to secure financial transactions via mobile commerce? Due to the advent of the Internet, electronic business transactions have exploded around the globe. Generally speaking, M-Commerce creates more security concerns than traditional E-Commerce. Mobile payment is defined as any payment transaction involving the purchase of goods or services that is completed with a wireless device. In this paper let us have a brief survey on security issues when designing, implementing, and deploying secure m-payment systems with a focus on threats, vulnerabilities and risk. The first problems come from the limitation of wireless environments that are primarily from mobiles devises which have connection cost, low bandwidth, and low reliability. The second problem is the lack of sufficient security of existing mobile payment systems mainly due to improper protocol design and deployment of lightweight cryptographic operations. . .
