چکیده

Based on analysis of security problems from malicious hosts, a special undetachable threshold digital signature scheme is proposed. This scheme uses a cryptosystem based on conic curves and achieves the most important security characteristic of protecting mobile agents against malicious hosts, that is, undetachability. Furthermore, this scheme solves the case where a host can force an agent to commit to a sub-optimal transaction. Computational studies show that this scheme is superior to the RSA-based undetachable threshold digital signature scheme.

An Efficient Conic Curve Threshold Digital Signature

We propose a new threshold signature scheme based on conic curve. The security of the proposed threshold signature scheme is based on the difficulty of computing the DLP in conic curve groups. It can resist some of the known attacks. Since an exciting characteristic of conic is both encoding and decoding over conic are easily implemented, it can be used in the mobile payment system with the lim...

A Public-Key Cryptosystem Scheme on Conic Curves over the Ring Zn

A public key cryptosystem scheme is proposed that are based on conic curves over the ring Zn. Our scheme is motivated by KMOV scheme on elliptic curves, but our scheme remove some restrictive condition from KMOV scheme and constructed on conic curves. Its security bases on the difficulty of factoring a composite number n, just like RSA. It can resist some of the known attacks on RSA. We also co...

A Distributed E-Business System Based on Conic Curve

A distributed E-Business System based on conic curve is proposed. This scheme is composed of two parts, constructing license and validating license. Because the security of license is determined by private key, not the arithmetic itself, user can not construct new license by given license and the public key as long as the private key is not leaked. Since encoding and decoding over conic are eas...

Secure Mobile Agent Using Strong Non-designated Proxy Signature

It is expected that mobile agent will be widely used for electronic commerce as an important key technology. If a mobile agent can sign a message in a remote server on behalf of a customer without exposing his/her private key, it can be used not only to search for special products or services, but also to make a contract with a remote server. To construct mobile agents, [KBC00] used an RSA-base...
