摘要： A system described herein includes a receiver component that receives source code from a computer-readable medium of a computing device and a static analysis component that executes a points-to analysis algorithm over the source code to cause generation of a points-to graph, wherein the points-to graph is a directed graph that comprises a plurality of nodes and a plurality of edges, wherein nodes of the points-to graph represent pointers in the source code and edges represent inclusion relationships in the source code. The system also includes an inference component that infers target types for generic pointers in the source code based at least in part upon known type definitions and global variables in the source code.

摘要： To render digital content encrypted according to a content key (KD) on a first device having a public key (PU1) and a corresponding private key (PR1), a digital license corresponding to the content is obtained, where the digital license includes the content key (KD) therein in an encrypted form. The encrypted content key (KD) from the digital license is decrypted to produce the content key (KD), and the public key (PU1) of the first device is obtained therefrom. The content key (KD) is then encrypted according to the public key (PU1) of the first device (PU1 (KD)), and a sub-license corresponding to and based on the obtained license is composed, where the sub-license includes (PU1 (KD)). The composed sub-license is then transferred to the first device.

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： 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 only one or more target programs to be able to obtain the data from the ciphertext. In accordance with another aspect, a bit string is received from a calling program. An identifier of the calling program is checked to determine whether the calling program is allowed to access data encrypted in ciphertext of the bit string. The data is decrypted using public key decryption and returned to the calling program only if the calling program is allowed to access the data.

摘要： Mechanisms are disclosed that may allow certain memory access control algorithms to be implemented efficiently. When memory access control is based on controlling changes to an address translation map (or set of maps), it may be necessary to determine whether a particular map change would allow memory to be accessed in an impermissible way. Certain data about the map may be cached in order to allow the determination to be made more efficiently than performing an evaluation of the entire map.
