Abstract:

The security of mobile agent is an obstacle that has to be faced in mobile agent technology. In order to protect the information confidentiality in the payments using mobile agents,this paper presents a secure payment protocol based on mobile agents by adopting the verifiable secret sharing scheme of Pedersen.Moreover,the per-form ances of the proposed protocol,including the security,the non-repudiation and the running efi ciency,are ana-lyzed and discussed in detail.The results show that,compared with the existing methods,the proposed protocol is more practically valuable because it ensures the security of payment information with ease while possessing a suit-able running eficiency,and improves the security and flexibility of the payment system.

Key words: verifiable secret sharing, mobile agent, payment protocol, non-repudiation, running eficiency
