    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： 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 computer system 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.

    摘要： An apparatus, system and method of secure communications from a human interface device are provided. The apparatus, system, and method receive input data and calculate encrypted data from the input data using a secure credential. In one embodiment the apparatus, system, and method request and receive a single instance credential and calculate the encrypted data using the secure credential and the single instance credential. The encrypted data may be a secure authorization that may be valid for one use. Communication of the encrypted data through networks and communicating devices is secure. The encrypted data may not be decrypted even if intercepted without the secure credential. The apparatus, system, and method enable secure communications from the human interface device.

    摘要： A method and apparatus are disclosed in a data processing system for establishing virtual endorsement credentials. The data processing system includes a hardware trusted platform module (TPM). Logical partitions are generated in the system. A different virtual TPM is generated for each one of the logical partitions. For each one of the logical partitions, the virtual TPM that was generated for the logical partition then dynamically generates a virtual endorsement key, which is stored only within a corresponding virtual TPM. Using the virtual endorsement key, each virtual TPM also generates a virtual endorsement credential for use by the logical partition that includes the virtual TPM. The virtual endorsement credential is generated within the data processing system without the data processing system or its devices accessing a trusted third party that is external to the data processing system.

    摘要： A method, system and computer program product for securing decrypted files in a shared environment. A filter driver in a kernel space may be configured to control service requests to encrypted files stored in a shared area, e.g., a shared directory on a disk unit, accessible by multiple users. The filter driver may receive a service request to open an encrypted document in the shared area issued from an authorized user. Upon receiving the encrypted data, the filter driver may decrypt the encrypted data. The filter driver may subsequently store the decrypted data in a file in a non-shared area, e.g., a non-shared directory. The non-shared area may be accessible only by the authorized user that requested access to the encrypted file. By storing the decrypted data in a file in the non-shared area, a file once decrypted may be protected in a file sharing environment.
