摘要： A method for a plurality of key cache managers for a plurality of localities to share cryptographic key storage resources of a security chip, includes: loading an application key into the key storage; and saving a restoration data for the application key by a key cache manager, where the restoration data can be used by the key cache manager to re-load the application key into the key storage if the application key is evicted from the key storage by another key cache manager. The method allows each of a plurality of key cache managers to recognize that its key had been removed from the security chip and to restore its key. The method also allows each key cache manager to evict or destroy any key currently loaded on the security chip without affecting the functionality of other localities.
摘要翻译：一种用于多个地区的多个密钥高速缓存管理器用于共享安全芯片的加密密钥存储资源的方法，包括：将应用密钥加载到密钥存储器中; 并且由密钥高速缓存管理器保存用于应用密钥的恢复数据，其中如果应用密钥从另一个密钥存储器被逐出，密钥高速缓存管理器可以使用恢复数据将应用密钥重新加载到密钥存储器中密钥缓存管理器。该方法允许多个密钥高速缓存管理器中的每一个识别出其密钥已经从安全芯片中移除并恢复其密钥。该方法还允许每个密钥缓存管理器驱逐或销毁安全芯片上当前加载的任何密钥，而不影响其他地方的功能。

摘要： A motherboard for a computer system is presented which provides a trusted platform by which operations can be performed with an increased level trust and confidence. The basis of trust for the motherboard is established by an encryption coprocessor and by code which interfaces with the encryption coprocessor and establishes root of trust metrics for the platform. The encryption coprocessor is built such that certain critical operations are allowed only if physical presence of an operator has been detected. Physical presence is determined by inference based upon the status of registers in the core chipset on the motherboard.

摘要： A method and system for ensuring security-compliant creation and signing of endorsement keys of manufactured TPMs. The endorsement keys are generated for the TPM. The TPM vendor selects an N-byte secret and stores the N-byte secret in the TPM along with the endorsement keys. The secret number cannot be read outside of the TPM. The secret number is also provided to the OEM's credential server. During the endorsement key (EK) credential process, the TPM generates an endorsement key, which comprises both the public key and a hash of the secret and the public key. The credential server matches the hash within the endorsement key with a second hash of the received public key (from the endorsement key) and the vendor provided secret. The EK certificate is generated and inserted into the TPM only when a match is confirmed.

摘要： A method is presented for implementing a trusted computing environment within a data processing system. A hypervisor is initialized within the data processing system, and the hypervisor supervises a plurality of logical, partitionable, runtime environments within the data processing system. The hypervisor reserves a logical partition for a hypervisor-based trusted platform module (TPM) and presents the hypervisor-based trusted platform module to other logical partitions as a virtual device via a device interface. Each time that the hypervisor creates a logical partition within the data processing system, the hypervisor also instantiates a logical TPM within the reserved partition such that the logical TPM is anchored to the hypervisor-based TPM. The hypervisor manages multiple logical TPM's within the reserved partition such that each logical TPM is uniquely associated with a logical partition.

摘要： A Method and system for ensuring security-compliant creation and signing of endorsement keys of manufactured trusted platform modules. The endorsement keys are generated for the trusted platform module (TPM). The TPM vendor selects an N-byte secret and stores the N-type secret in the trusted platform module along with the endorsement keys. The secret number cannot be read outside of the trusted platform module. The secret number is also provided to the credential server of the original equipment manufacturer. During the endorsement key (EK) credential process, the trusted platform module generates an endorsement key, which comprises both the public key and a hash of the secret and the public key. The credential server matches the hash within the endorsement key withy a second hash of the received public key (from the endorsement key) and the vendor provided secret. The EK certificate is generated and inserted into the trusted platform module only when a match is confirmed.
