However, pattern password authentication mechanism is incapable of protecting users from losses when a user's login credential information is stolen. We propose an identity(More)
A flexible task model (FTM) is proposed for modeling the relationship between grid tasks. We investigate the problem of scheduling grid computing tasks under FTM using light-trails in WDM networks to supporting the data communication between the tasks. Simulation results show that our proposed task scheduling algorithm under FTM significantly reduces the(More)
