摘要： Systems and methods that support storage device content authentication are provided. A system that verifies storage device content received from a storage device may comprise, for example, a security processor coupled to the storage device. The security processor may be adapted to receive a partitioned storage device region from the storage device. The partitioned storage device region may comprise, for example, regional content and first hashed regional content. The security processor may generate, for example, second hashed regional content by performing a hashing function on the regional content received by the security processor. The security processor may compare, for example, the first hashed regional content to the second hashed regional content. The security processor may verify the regional content received by the security processor if the first hashed regional content is the same as the second hashed regional content.

The secure key may be a master key, a work key and/or a scrambling key. The digitally signed secure key may be received at the second location and the digitally signed secure key may be decrypted to obtain a decrypted digitally signed secure key.

摘要： A one-time-programmable (OTP) module includes OTP memory and OTP input/output (I/O) that performs error correction operations. The OTP module may be used in a data communications system. The error correction operations operate according to one of a plurality of supported coding schemes. In one embodiment, the error correction operations are based upon Hamming code operations. The coding scheme employed by the error correction operations is set by a code control input. The code control input is chosen based upon the inherent quality of the OTP memory. The OTP module may thus be incorporated into any of a variety of processes, each of which has its own OTP memory quality.

摘要： Herein described is a system and method for improving the performance in which data packets are processed in a set-top-box. The system determines and stores one or more values into a memory. The one or more values in memory are subsequently utilized when a firmware is executed. These values are used to efficiently index locations within one or more data packets, such that processing performance is improved. Based on the types of packets received by the set-top-box, the hardware assistance provided by the system may be gradually increased or attenuated to optimize the performance in which the data packets are processed. The method involves determining the one or more values, storing the one or more values in a memory, and using said one or more values to effectively index one or more data fields in the one or more data packets.
