A method and apparatus for trusted authentication and logon is disclosed. A trusted platform module (TPM) based logon method is presented for authentication and access. A user registers an identity with an identity provider that is tightly bound to the user's specific platform, e.g., the TPM. If the user decides to login, for example to a service provider using this identity, the identity provider challenges the user to provide the correct credentials. The credentials consist of a TPM generated ticket, that is, a credential chain. This allows the user to login without the need for a password at the identity provider.

Deploying an encrypted entity on a trusted entity is illustrated herein. A method includes, at a trusted entity, wherein the trusted entity is trusted by an authority as a result of providing a verifiable indication of certain characteristics of the trusted entity meeting certain requirements, receiving an encrypted entity from an untrusted entity. The untrusted entity is not trusted by the authority. At the trusted entity, a trust credential from the authority is used to obtain a key from a key distribution service. The key distribution service is trusted by the authority. The key is used to decrypt the encrypted entity to allow the encrypted entity to be deployed at the trusted entity.

Systems and methods include establishing a secure communication between an application module and a sensor module. The application module is executing on an information-handling machine, and the sensor module is coupled to the information-handling machine. The establishment of the secure communication is at least partially facilitated by a mutually trusted module.

To prevent piracy, audiovisual content is encrypted prior to transmission to consumers. A low-cost, high-security cryptographic rights module (such as a smartcard) enables devices such as players/displays to decode such content. Security-critical functions may be performed by the cryptographic module in a manner that allows security compromises to be addressed by upgrading or replacing cryptographic modules, thereby avoiding the need to replace or modify other (typically much higher-cost) components. The security module contains cryptographic keys, which it uses to process rights enablement messages (REMs) and key derivation messages (KDMs). From a REM and KDM, the security module derives key data corresponding to content, uses public key and/or symmetric cryptography to re-encrypt the derived key data for another device, and provides the re-encrypted key data to the decoding device. The decoding device then uses cryptographic values derived from the re-encrypted key data to decrypt the content.

A device, system, and method for providing processor-based data protection on a mobile computing device includes accessing data stored in memory with a central processing unit of the mobile computing device and determining that the accessed data is encrypted data based on a data included in one or more control registers of the central processing unit. If the data is determined to be encrypted data, the central processing unit is to decrypt the encrypted data using a cryptographic key stored in the central processing unit. The encrypted data may also be stored on a drive of the mobile computing device. The encryption state of the data stored on the drive is maintained in a drive encryption table, which is used to update a memory page tables and the one or more control registers.

Technologies for improving platform initialization on a computing device include beginning initialization of a platform of the computing device using a basic input/output system (BIOS) of the computing device. A security co-processor driver module adds a security co-processor command to a command list when a security processor command is received from the BIOS module. The computing device establishes a periodic interrupt of the initialization of the platform to query the security co-processor regarding the availability of a response to a previously submitted security co-processor command, forward any responses received by the security co-processor driver module to the BIOS module, and submit the next security co-processor command in the command list to the security co-processor.

A method, system, and/or computer program product propagates system upgrades to peer computers in a peer community. A peer community is defined by identifying peer computers that each have a copy of a same system component. Each of the peer computers in the peer community is autonomous, such that no peer computer controls another peer computer. A test computer is selected from the peer computers. An upgrade to a system component on the test computer is installed and tested. In response to the upgrade to the system component functioning properly within the test computer, a message is sent to other peer computers within the peer community recommending that they install the upgrade.

Technologies for secure programming of a cryptographic engine include a computing device with a cryptographic engine and one or more I/O controllers. The computing device establishes one or more trusted execution environments (TEEs). A TEE generates a request to program the cryptographic engine with respect to a DMA channel. The computing device may verify a signed manifest that indicates the TEEs permitted to program DMA channels and, if verified, determine whether the TEE is permitted to program the requested DMA channel. The computing device may record the TEE for a request to protect the DMA channel and may determine whether the programming TEE matches the recorded TEE for a request to unprotect a DMA channel. The computing device may allow the request to unprotect the DMA channel if the programming TEE matches the recorded TEE. Other embodiments are described and claimed.

By comparing a chip unique password, certification for activating a debug function can be established on the chip unique password. Thus, even when the chip unique password is lost due to negligence, not only certification for activating debugging on other motherboards of the same model number can remain unaffected, but also risks caused by replacing a chip or by a private key leakage from a system manufacturer are eliminated.

A method and apparatus for renewing cryptographic material are disclosed. In the method and apparatus a cryptographic material renewal entity of a computing resource service provider detects that cryptographic material stored by a secure module is to be renewed. Renewing the cryptographic material may include rekeying a private key associated with a certificate. Further, a digital certificate may be renewed, and the renewed certificate may be provided for use by the computing resource. The cryptographic material is used to fulfill requests made by a computing resource provisioned by the computing resource service provider for a customer. The renewed cryptographic material is provided to the secure module, whereby the renewed cryptographic material is used by the secure module to fulfill further requests made by the computing resource.
