摘要： Systems and methods for systems and methods for reliably broadcasting content to a plurality of users and facilitating distribution of portions of the broadcast content that either were not received by particular users, or were received with errors. In one embodiment, a wireless communication system is configured to broadcast content from a content source to a plurality of user devices. The content source is configured to provide the content to a base station. The base station parses the content into a plurality of segments and associates sequential identifiers with each of the segments. The content is then broadcast to each of the user devices. An identifier of an alternative data source is also provided to the user devices. When a mobile station receives the segments, it examines the segment identifiers to identify missing segments. The segments are then retrieved from the alternative data source identified by the base station.

摘要： Apparatus and method for provisioning an access key used for a controlled access broadcast service is disclosed. In one aspect, a method for secure processing in a device that securely stores a secret key comprises receiving a plurality of challenges from a network, generating a plurality of ciphering keys based on the secret key and the plurality of challenges, and generating an access key based on the plurality of ciphering keys.

摘要： The REX cryptosystem presented herein is a variant of the NTRU cryptosystem. In the REX cryptosystem, a primary ring RXOR and two secondary rings RXOR,q and RXOR,p are used to reduce the number of operations required to compute the keys, to perform the encryption process, and to perform the decryption process. The REX cryptosystem may also be implemented using Walsh-Hadamard transformations to significantly increase speed.
