摘要： A system and method for securing data on a wireless device. A secured zone is defined by a boundary sensor. A data processing system is coupled to the boundary sensor and a wireless device. The data processing system includes a boundary controller for determining whether the wireless device has entered the secured zone. If the wireless device has entered the secured zone, a security controller queries the wireless device to determine whether the software stored on the wireless device has been subjected to unauthorized alteration. If the software has not been subjected to unauthorized alteration, the security controller enables the wireless device for operation within the secured zone.

摘要： A system and method for securing data on a wireless device. A secured zone is defined by a boundary sensor. A data processing system is coupled to the boundary sensor and a wireless device. If the data processing system detects that the signal strength of the wireless device has fallen below a first predetermined value for longer than a second predetermined value, the data processing system deletes a digital certificate corresponding to the wireless device from memory. Thus, when the wireless device is reintroduced into the secured zone, in response to determining that a digital certificate corresponding to the wireless device is not stored in memory, the disabling module disables the wireless device from operation within the secured zone.

摘要： A method for theft deterrence of a computer system is disclosed. The computer system includes a trusted platform module (TPM) and storage medium. The method comprises providing a binding key in the TPM; and providing an encrypted symmetric key in the storage medium. The method further includes providing an unbind command to the TPM based upon an authorization to provide a decrypted symmetric key; and providing the decrypted symmetric key to the secure storage device to allow for use of the computer system. Accordingly, by utilizing a secure hard disk drive (HDD) that requires a decrypted key to function in conjunction with a TPM, a computer if stolen is virtually unusable by the thief. In so doing, the risk of theft of the computer is significantly reduced.

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 reload 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 is 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 method and system for remotely storing a user's admin key to gain access to an intranet is presented. The user's admin key and intranet user identification (ID) are encrypted using an enterprise's public key, and together they are concatenated into a single backup admin file, which is stored in the user's client computer. If the user needs his admin file and is unable to access it in a backup client computer, he sends the encrypted backup admin file to a backup server and his unencrypted intranet user ID to an intranet authentication server. The backup server decrypts the user's single backup admin file to obtain the user's admin key and intranet user ID. If the unencrypted intranet user ID in the authentication server matches the decrypted intranet user ID in the backup server, then the backup server sends the backup client computer the decrypted admin key.

摘要翻译： 介绍一种用于远程存储用户管理密钥以访问内联网的方法和系统。 用户的管理密钥和内部网用户标识（ID）使用企业的公钥进行加密，并将它们并入一个备份管理文件，该文件存储在用户的客户端计算机中。 如果用户需要他的管理员文件，并且无法在备份客户端计算机中访问它，则他将加密的备份管理文件发送到备份服务器，并将其未加密的内部网用户ID发送到内部网认证服务器。 备份服务器解密用户的单备份管理文件，获取用户的管理密钥和内部网用户ID。 如果身份验证服务器中未加密的Intranet用户ID与备份服务器中的解密内网用户ID匹配，则备份服务器将备份客户端计算机发送解密的管理密钥。

摘要： An architecture for a distributed data processing system comprises a system-level service processor along with one or more node-level service processors; each are uniquely associated with a node, and each is extended to comprise any components that are necessary for operating the nodes as trusted platforms, such as a TPM and a CRTM in accordance with the security model of the Trusted Computing Group. These node-level service processors then inter-operate with the system-level service processor, which also contains any components that are necessary for operating the system as a whole as a trusted platform. A TPM within the system-level service processor aggregates integrity metrics that are gathered by the node-level service processors, thereafter reporting integrity metrics as requested, e.g., to a hypervisor, thereby allowing a large distributed data processing system to be validated as a trusted computing environment while allowing its highly parallelized initialization process to proceed.

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 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.
