摘要：
A method, apparatus, and computer program product are described for implementing a trusted computing environment within a data processing system. The data processing system includes a primary hardware trusted platform module (TPM) and a secondary hardware backup TPM. The data processing system also includes multiple logical partitions. The primary hardware TPM is used to provide trusted computing services to the logical partitions. A determination is made as to whether the primary hardware TPM is malfunctioning. If a determination is made that the primary hardware TPM is malfunctioning, the secondary hardware TPM is designated as a new primary hardware TPM and is utilized instead of the primary TPM to provide trusted computing services to the logical partitions.
