A security scheme of electronic commerce for mobile agents uses undetachable digital signatures
Yang Shi, Liming Cao, Xiaoping Wang · 2004
A security scheme to protect mobile agents against malicious hosts in electronic commerce is proposed. This scheme uses undetachable digital signatures technique and public key encryption algorithms based on ellipse curves to achieve following characteristics: first, the identity of a shop and a customer cannot be forged. Second, the requirements of a customer and the bid of a shop cannot be detached. Third, the identity and the bid information of a shop keep private against other shops. Finally, it's able to resist replay attacks. Furthermore, the scheme also has some computational advantages compared to similar schemes that use RSA cryptosystem.
