It provides online transactions within a glance to the customers. Use these services at anytime and anywhere. These applications need a high level of security due to the open nature of wireless networks. Furthermore, security is harder to implement on the mobile platform because of the resource constraints of mobile handheld devices. Therefore, security methods for protecting traditional computer communications need to be revisited so as to certify that electronic transactions involving mobile devices can be secured and implemented in a successful manner. In this paper, we reflect on some important security issues with deployment of strong security concerns via m-transactions. Keywords M - Commerce, security issues, wireless security, Bluetooth and cryptography. 1. INTRODUCTION Mobile commerce is equivalent to wireless telecommunication technologies. These wireless devices include all hand held devices like laptops, palmtops, tablets, i-pads, smart phones etc. Through these devices financial and promotional activities are conducted. The ability to conduct mobile transactions can draw attention of new customers and keep current ones loyal. Generally a mobile transaction happens when a customer uses the web enabled services of a web dealer and after negotiations and communications, choose to make an order and do payment. The order and payment information is broadcasted from the mobile device to a base wireless station and from there, through the mobile communication infrastructure of the service provider, to the wireless application gateway of the dealer It is expected that mobile commerce services would be the next biggest growth area in the telecommunications market.

Today, mobile communication is a mature technology, transit from 2G to 3G with high level of customer acceptance. 3G technology in mobile provides countless applications. And there will be a drastic expansion of this technology in near future also. As there is open nature of wireless network, security is main concern in this platform. Because no mobile commerce strategy is complete without thorough understanding of security. In this paper, we consider two main parts of m- commerce that are significant to security, Security challenges– in m-commerce, all data are transmitted via a mobile telecommunication network. Here, we discuss all security challenges including handset, language and wireless security concerns.
