Abstract
In this paper, we propose a solution for building a secure e-transaction system based on a combination of theorems like proxy, cross validation and blind signature schemes with mobile agent technology. We make the identity of mobile agent unknown for all the service hosts participating in the e-transaction to ensure the equity of service provision. The proposed solution is designed with the aim of providing: (1) the parity or equity of service provision to all agent hosts. (2) chasing and punish of malicious mobile agents in case of attacking a service host as (3) allows agent host to authenticate or validate the product or the service which he is about to receive is certainly the one he request or pay for, (4) a solution for the problem of conspired truncation attack which the mobile agent faces during its dynamic migration between service hosts. The security properties of the proposed solution are analysed and compared with the most related work.
