Zusammenfassung
Delivering electronic goods over the Internet is one of the e-commerce
applications that will proliferate in the coming years. Certified
e-goods delivery is a process where valuable e-goods are exchanged
for an acknowledgement of their reception. This paper proposes an
efficient security protocol for certified e-goods delivery with the
following features: (1) it ensures strong fairness for the exchange
of e-goods and proof of reception, (2) it ensures non-repudiation
of origin and non-repudiation of receipt for the delivered e-goods,
(3) it all ows the receiver of e-goods to verify, during the exchange
process, that the e-goods to be received are the one he is signing
the receipt for, (4) it uses an off-line and transparent semi-trusted
third party (STTP) only in cases when disput es arise, (5) it provides
the confidentiality protection for the exchanged items from the STTP,
and (6) achieves these features with less computational and communicational
overheads than related protocols.
