with the increasing development of the Internet and electronic commerce, electronic payment systems have gradually become an important issue nowadays. Business-to-business E-commerce model involves a complex process with large transaction size, so that B2B payment is the next focus of the popular research topics on electronic commerce. Though there are many existing e-payment protocols designed for transactions of low-to-medium volumes and medium-to-high value, these schemes only suit for B2C and C2C E-commerce model. iKP is one of the most popular macro payment schemes using in B2C model. Considering that B2B payment is evolution of B2C payment, through analyzing the similarity and difference between B2B and B2C payment, as well as pointing out the virtues and drawbacks of iKP, this paper describes an improved iKP protocol based on B2B. The proposed protocol not only preserves the security properties of iKP but also achieves the needs of B2B payment. The future work will concentrate on satisfying different payment conditions of B2B e-payment.
