Abstract

The Trusted Platform Module (TPM) is an embedded cryptographic processor and non-volatile storage device which designed to be tamper-proof. There are many sensitive data in the TPM. We present a sensitive data backup and recovery mechanism in the TPM used in some abnormal situations such as power outage to ensure the data consistency and analyze the feasibility of this mechanism in detail. Besides, we use the backup stack and mark zone cyclically to avoid hardware malfunction in this mechanism.
