An Efficient Off-Line Reputation Scheme Using Articulated Certificates
نویسندگان
چکیده
A common feature practical reputation schemes is that they are on-line which results in restrictions to both availability and scalability. In order to overcome these two problems we propose an off-line reputation scheme based on public key certificates. We introduce the idea of articulated certificates which use proxy signatures to increase the efficiency of reputation verification. As well as being well-suited to our problem such linked certificates may be of independent interest.

An efficient certificateless signcryption scheme in the standard model
Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. A signcryption scheme is an important primitive in cryptographic protocols which ...
متن کاملTrust Management in an Ad hoc Network of Cellular Phones used in Emergency Conditions
We study the unique trust management, and more precisely reputation management and revocation of malicious ad hoc nodes used for emergency communications. Unlike in centralized systems, reputation management and revocation in ad hoc networks is non-trivial. This difficulty is due to the fact that the nodes have to collaboratively calculate the reputation value of a particular node and then revo...
متن کاملA collusion mitigation scheme for reputation systems
Reputation management systems are in wide-spread use to regulate collaborations in cooperative systems. Collusion is one of the most destructive malicious behaviors in which colluders seek to affect a reputation management system in an unfair manner. Many reputation systems are vulnerable to collusion, and some model-specific mitigation methods are proposed to combat collusion. Detection of col...

The paper proposes an algorithm to calculate the switching angles using harmonic elimination PWM (HEPWM) scheme for voltage source inverter. The algorithm is based on curve fittings of a certain polynomials functions. The resulting equations require only the addition and multiplication processes; therefore, it can be implemented efficiently on a microprocessor. An extensive angle error analysis...
