摘要： Methods and systems are provided for cryptographically protecting secure content in connection with a graphics subsystem of a computing device. Techniques are implemented to encrypt the contents of video memory so that unauthorized software cannot gain meaningful access to it, thereby maintaining confidentiality. Moreover, a mechanism for tamper detection is provided so that there is awareness when data has been altered in some fashion, thereby maintaining integrity. In various embodiments, the contents of overlay surfaces and/or command buffers are encrypted, and/or the GPU is able to operate on encrypted content while preventing its availability to untrusted parties, devices or software.

摘要： To render digital content determined to be in an encrypted rights-protected form, each available license corresponding to the digital content to be rendered is identified, where each such license includes a decryption key (KD) for decrypting the digital content to be rendered, and where the decryption key (KD) in the license is encrypted according to a public key (PU) (PU(KD)). One of the identified licenses is selected and (KD) is obtained from the selected license by obtaining (PU(KD)) from the selected license and decrypting (PU(KD)) according to a private key (PR) corresponding to (PU) to produce (KD). The digital content is decrypted with (KD), and the decrypted digital content is provided for actual rendering.

摘要： Theft of decompressed digital content as the content is being rendered is prevented. A requested slow-down of the rendering of the content is detected. Transfers of relatively large amounts of data are detected. A re-compressor-based requested slow-down of the rendering of the content is detected. A re-compressor re-compressing the content is detected. In each situation, the detected activity is presumably initiated by a content thief attempting to steal the content. In each situation, the detected activity is responded to in a manner designed to frustrate the presumed attempt of the content thief to steal the content.

摘要： In accordance with certain aspects, data is received from a calling program. Ciphertext that includes the data is generated, using public key encryption, in a manner that allows the data to be obtained from the ciphertext only if one or more conditions are satisfied. In accordance with another aspect, a bit string is received from a calling program. Data in the bit string is decrypted using public key decryption and returned to the calling program only if one or more conditions included in the bit string are satisfied.

摘要： A secure processor is operable in normal and preferred modes, and includes a security kernel instantiated when the processor enters into preferred mode and a security key accessible by the security kernel during preferred mode. The security kernel employs the accessed security key to authenticate a secure application, and allows the processor to be trusted to keep hidden a secret of the application. To instantiate the application, the processor enters preferred mode where the security key is accessible, and instantiates and runs the security kernel. The security kernel accesses the security key and applies same to decrypt a key for the application, stores the decrypted key in a location where the application will expect same, and instantiates the application. The processor then enters the normal mode, where the security key is not accessible.
摘要翻译：安全处理器在正常和优选模式下可操作，并且包括当处理器进入优选模式时实例化的安全内核以及在优选模式期间由安全内核访问的安全密钥。安全内核使用访问的安全密钥来认证安全应用程序，并允许处理器被信任以隐藏应用程序的秘密。为了实例化应用程序，处理器进入可访问安全密钥的首选模式，并实例化和运行安全内核。安全内核访问安全密钥并应用该密钥对应用程序的密钥进行解密，将解密的密钥存储在应用程序期望相同的位置，并实例化应用程序。然后，处理器进入正常模式，其中安全密钥不可访问。
