Abstract: Systems and methods for prioritizing adaptive bit rate distribution of content are provided. In some aspects, a method includes identifying a plurality of content streams. Each of the plurality of content streams is associated with a variant feature of content to be delivered to the client device. Each variant feature of the content comprises at least one of a bit rate and a non-bit rate feature. The method also includes determining a priority of each of the plurality of content streams relative to one another based at least on the non-bit rate feature associated with each of the plurality of content streams. The method also includes providing an indication of the priority of each of the plurality of content streams to the client device.

Abstract: A broadband gateway may manage confidential data associated with users in a home network managed and/or serviced by the broadband gateway. The broadband gateway may store the user confidential data broadband gateway in a distributed manner, wherein the confidential data may be divided into a plurality of portions and stored separately in multiple storage locations or devices. When users authorize the transfer of the confidential data, all portions may be communicated to enable aggregating them such that the confidential data may be obtained. The user confidential data may be encrypted. The broadband gateway may securely communicate and/or share the user confidential user data. This may be achieved by tracking communication of the user confidential data, by using tags incorporated into the data. The broadband gateway may also ensure that communicated confidential data is rendered unusable under certain conditions, based on use for various timing tags for example.

Abstract: Secure functions may be accessed via an authentication process utilizing a password that may be generated within a chip integrated on a device. The password may be unique per chip location, per challenge and/or per chip. The location of the chip may be determined based on GPS information and securely stored and securely communicated to an external entity. Two or more of the chip location, a generated random number sample and a key from a table of keys may be passed to a hash function that may generate a password. An external entity attempting access may be challenged to respond with a password that matches the password generated by the hash function. The response may be compared with the password generated by the hash function and access to one or more secure functions may be granted based on the comparison.

Abstract: A system and method that enables secure system boot up with a restricted central processing unit (CPU). The system includes a memory, a segmenting device, and a security sub-system. The memory is a NAND flash memory with a block structure that comprises a guaranteed block and non-guaranteed blocks. The guaranteed block is guaranteed to be useable. A boot code is segmented into boot code segments and the boot code segments are stored separately in the guaranteed and non-guaranteed blocks. The security sub-system is configured to locate the boot code segments stored in the non-guaranteed blocks and validate them independently based on data in the guaranteed block. The security sub-system is further configured to assemble the boot code segments into the boot code and execute the boot code.
