Secure Authentication Protocol for Mobile Payment

With the increasing popularity of fintech, i.e., financial technology, the e-commerce market has grown rapidly in the past decade, such that mobile devices enjoy unprecedented popularity and are playing an ever ncreasing role in e-commerce. This is especially true of mobile payments, which are attracting increasing attention However, the occurrence of many traditional financial mishaps has exposed the challenges inherent in online authentication technology that is based on traditional modes of realizing the healthy and stable development of mobile payment. In addition, this technology ensures user account security and privacy. In this paper, we propose a Secure Mutual Authentication Protocol （SMAP） based on the Universal 2nd Factor （U2F） protocol for mobile payment. To guarantee reliable service, we use an asymmetric cryptosystem for achieving mutual authentication between the server and client, which can resist fake servers and forged terminals. Compared to the modes currently used, the proposed protocol strengthens the security of user account information as well as individual privacy throughout the mobile-payment transaction process. Practical application has proven the security and convenience of the proposed protoco

A Trusted Mobile Payment Environment Based on Trusted Computing and Virtualization Technology

In this paper, we propose a trusted mobile payment environment （TMPE） based on trusted computing and virtualization technology. There are a normal operating system （OS） and a trusted OS （TOS） in TMPE. We store the image of TOS in a memory card to hinder tampering. The integrity of TOS is protected by means of a trusted platform module （TPM）. TOS can only be updated through a trusted third party. In addition, virtualization technology is applied to isolate TOS from normal OS. Users complete ordinary affairs in normal OS and security-sensitive affairs in TOS. TMPE can offer users a highly protected environment for mobile payment. Moreover, TMPE has good compatibility in different hardware architectures of mobile platforms. As the evaluation shows, TMPE satisfies the requirement of mobile payment well.

Analysis and Improvement on a Mobile Payment Protocol with Outsourced Verification in Cloud Service

Mobile wallet is a very convenient means of mobile payment to allow the clients to conduct the payment via their mobile devices. To reduce the computation burden of resources-constraint mobile devices, a few mobile wallet protocols with outsourced verification in cloud computing were proposed. But in some of the protocols, there exist the risk of a colluding attack of the customer and the untrusted cloud server. In this paper, we propose an improved protocol, in which the payment information is protected by Hash function and random number. The malicious customer and cloud server cannot change the payment information to conduct a collusion forgery attack to defraud the merchant. The security analysis indicates that the proposed improved protocol can enhance the security in terms of correctness, unforgeability and traceability without increasing the computational burden.
