| Abstract: | This paper presents an agent-based secure payment protocol that protects merchants and customers to exchange information. The difference between the prototype and other payment systems is that this prototype uses different cryptography algorithms that depend on the message's importance and its urgency. Also, this prototype adds another level of security to protect both merchants and customers. Further, this prototype employs an adaptive waiting message time. The use of changing cryptography algorithms or key sizes allow a faster message exchanging rate for urgent messages and a more secure message for those important messages. The additional security level pinpoints on some issues of the weakness of an opened network. Through the use of varying secret key size and increasing security levels, users are relieved of the task of exchanging information in an unreliable opened network environment. The adaptive waiting time feature prevents the transaction from aborting and restarting. Detailed expositions of varying cryptography algorithms, increasing security levels and waiting message dynamically, together with customer agents, merchant agents, and payment agents and how they interoperate are given in this paper. |
