Proposing a distributed algorithm to finding malevolent entities and improving security in e-commerce environments

In the context of e-commerce, the concept of security involves two areas: hard security and soft security. Hard security includes cryptography, information hiding and other standards, while soft security is associated with the methods which are based on trust. finding malevolent entities or malevolent agents are one of the most important concepts in e-commerce. Thus, sufficient attention should be paid to their security. Since the centralized security management architecture in e-commerce environment and cannot have enough effectiveness nor be implemented, with the aim of overcoming the limitations of centralized architectures, a distributed and dynamic algorithm is proposed to finding malevolent entities and improving security. This algorithm uses a distributed network. The results of this study indicate that the proposed algorithm is capable of finds malevolent entities and improves security in a fast and efficient manner.
