Trusted grid computing with security assurance and resource optimization

The security of Grid sites can be enhanced by upgrading its intrusion defense capabilities against its previous job success rate on Grid platforms. A new fuzzylogic trust model is proposed for distributed security enforcement across multiple Grid resources sites. The design is aimed at securing Grid resources with optimized resources subject to budget constraints. The performance of trusted Grid computing is verified by simulated trust integration over multiple Grid resource sites. The SARAH scheme scales well with increasing number of divisible user jobs and can sustain high efficiency, as more resource sites are added. Integrated trust and resource optimization make it possible to accommodate all user applications with low job drops and short waiting time. As a result, the Grid resources are better utilized for distributed execution of large number of user jobs
