A Secure Agent-Mediated Payment Protocol
نویسندگان
چکیده
While software agents have been employed in payment protocols, they are largely passive entities, i.e., they participate in the payment protocol but do not make decision. In this paper, we propose an agent-assisted payment protocol called LITESET/A+ that empowers the payment agent (PA) to perform encryption operation for its owner. This is realized by introducing a Trusted Third Party (TTP) in the payment system based on the SET protocol (Secure Electronic Transaction) and a novel signcryption-threshold scheme. In LITESET/A+, the PA and TTP collaborate together to ensure the same level of security as the SET specification. At the same time, with the signcryptionthreshold scheme, the PA is more flexible and autonomous during trading.

متن کاملAn ASEP (Advanced Secure Electronic Payment) Protocol Design Using 3BC and ECC (F^2) Algorithm
Unlike SET (Secure Electronic Transaction) protocol. This paper proposes an ASEP (Advanced Secure Electronic Payment) protocol, which uses ECC (Elliptic Curve Cryptosystem with F2 m not Fp) [1, 2, 3], SHA (Secure Hash Algorithm) and 3BC (Block Byte Bit Cipher) instead of RSA and DES. To improve the strength of encryption and the speed of processing, the public key and the private key of ECC are...
