Evaluation of a Client Centric Payment Protocol Using Digital Signature Scheme with Message Recovery Using Self-Certified Public Key

摘要

In this work, we present a mobile e-payment scenario where the merchant entity has important connectivity restrictions, which is only able of communicating through short distance connections (Wi-Fi or Bluetooth). To protect the exchange of messages, our work describes a payment protocol centered in the client which applies digital signature with recovery using self-certified public keys. Additionally, security aspects have been analyzed and protocol implementation specifications have been presented.
