Abstract
The techniques presented herein provide for verifying the integrity of an encryption key log file generated on a data storage system. Encryption key activity events associated with a storage system's back-end storage drives are identified. A unique signature is generated for each encryption key activity event. Each encryption key activity event and its corresponding signature are stored in an audit log file. An audit log hash file is generated using the contents of the audit log file. At an external location, the audit log file and the audit log hash file are retrieved from the storage system. The integrity of the retrieved audit log file is verified by generating a local audit log hash file and comparing the local audit log hash file to the retrieved audit log hash file and determining if the local audit log hash file matches the retrieved audit log hash file.
