Abstract |
|
|
| This current work proposes a Hybrid Bat and Differential Evolution Algorithm (HBDEA) based on IaaS Cloud Partial Critical Path (IC-PCP) Replication and Improved Hyper Elliptic Curve Cryptography (HBDEAIPR with IHECC). The proposed HBDEAIPR algorithm applies a deadline constraint and a variable budget for replication to achieve its goals. Proposed Enhanced IC-PCP with Replication (EIPR) algorithm is increasing the likelihood of completing the execution of a scientific workflow application within a user-defined deadline in a public Cloud environment. The proposed HBDEA algorithm determines the parameters of tasks are the early start time and latest finish time to replicate workflow tasks to mitigate effects of performance variation of resources so that soft deadlines can be met. The proposed HBDEAIPR approach is verified by developing a IHECC system which authenticates the user not only based on task deadlines. Also, it uses secret-key and encrypted value for genuine users authentication in CC environment. Simulation experiments with well-known scientific workflow show that the proposed HBDEAIPR approach increases the likelihood of deadlines being met and reduces the total execution time of applications as the budget available for replication increases.
