The internet connection of cluster systems can provide the various and convenient services and can also increase the possibility of the external attacks. The malicious cracking causes the threat about the cluster system operating environment and can weaken the reliability toward the services of the cluster system base. Especially for most of huge web services based on cluster system like internet banking services, portal services etc., the trusted operational environment is very critical in order to guarantee their services is not compromised and then secure. Therefore, the integrity of the cluster system is important to enhance the reliability of the service provided based on the cluster system. This paper introduces the method for providing the integrity on the cluster system that includes the integrity of each cluster node and the integrity of programs to be provisioned. For the integrity of cluster node itself, we adopt the trusted booting based on TPM to each selected node, and for the integrity of programs to be provisioned, we adopt the digital signature and node authentication with private certificate authority (PCA).
