Abstract: Various embodiments provide a method and an apparatus for determining a trust status of a TPM, and a storage medium, and pertains to the field of data security technologies. In those embodiments, a verifier send an unsealing request to a host, so that the host unseals current PCR values in the TPM based on a seal key handle carried in the unsealing request, and sends verification information to the verifier based on the unseal verification key obtained after the unsealing. Therefore, any verifier that establishes an encrypted channel with the host can determine the trust status of the TPM in the host based on a second verification key transmitted on the encrypted channel, and there is no need to pre-deploy a remote attestation server to determine the trust status of the TPM.

Abstract: This application discloses a method and an apparatus for determining a trust status of a TPM, and a storage medium, and pertains to the field of data security technologies. The method includes: sending, by a verifier (102), an unsealing request to a host (101), so that the host (101) unseals current PCR values in the TPM based on a seal key handle carried in the unsealing request, and sends verification information to the verifier (102) based on the unseal verification key obtained after the unsealing. Therefore, any verifier (102) that establishes an encrypted channel with the host (101) can determine the trust status of the TPM in the host (101) based on a second verification key transmitted on the encrypted channel, and there is no need to pre-deploy a remote attestation server to determine the trust status of the TPM.

Abstract: A method and a system for controlling quality of service of a storage system, and a storage system. The method includes: collecting information about processing capabilities of the hard disks in the storage system and obtaining processing capabilities of the hard disks according to the information about processing capabilities; dividing a cache into multiple cache tiers according to the processing capabilities of the hard disks; and writing, for a cache tier in which dirty data reaches a preset threshold, data in the cache tier into at least one hard disk corresponding to the cache tier. The method avoids a phenomenon of preempting page resources in the cache.
Abstract translation: 一种用于控制存储系统的服务质量的方法和系统以及存储系统。 该方法包括：收集关于存储系统中的硬盘的处理能力的信息，并根据关于处理能力的信息获得硬盘的处理能力; 根据硬盘的处理能力将缓存分为多个缓存层; 并且对于其中脏数据达到预设阈值的高速缓存层，将高速缓存层中的数据写入到与缓存层对应的至少一个硬盘中。 该方法避免了在缓存中抢占页面资源的现象。
