Secure end-to-end mobile payment system

This paper proposes a secure end-to-end mobile payment system that allows performing secure end-to-end payment transaction using mobile devices. This system does not apply public key encryption as other existing systems, only message digests and private key cryptographic techniques are used which helps reduce computations for all relevant parties but still ensures all criteria of end-to-end security property. With this feature and the non-connectivity between client and payment gateway, this system overcomes all the limitations of wireless environment
