摘要: This document describes a system and method for managing communications between modules in a Controller Area Network (CAN) in a secure manner. In particular, the system employs a hierarchical key generation method that allows a module in the CAN to use a single ascendant key together with relevant identifiers to generate descendant keys for CAN identities in the Controller Area Network. These keys are then used by the broadcasting and receiving CAN modules to authenticate published messages.

摘要: A system for managing and distributing a blacklist of User Equipment IDs (UE IDs) in a network. The system comprises a number of groups of networks, each of the groups of networks comprise a blacklist server and a number of authentication servers. The system further comprises a Package Key Generator (PKG). The blacklist server is configured to: store a blacklist containing UE IDs that are not allowed to gain access to the network; transmit the blacklist to the plurality of authentication servers in the same group; receive a message; determine a content in the message is an order to add a new revoked UE ID to the blacklist; update the blacklist to include the new revoked UE ID; and send an update blacklist message to the plurality of authentication servers in the same group.

摘要: This invention is related to an Express Traversal (EXTRA) Network on Chip (NoC) comprising a number of EXTRA routers. The EXTRA NoC comprises a Buffer Write and Route Computation (BW/RC) pipeline, a Switch Allocation-Local (SA-L) pipeline, a Setup Request (SR) pipeline, a Switch Allocation-Global (SA-G) pipeline, and a Switch Traversal and Link Traversal (ST/LT) pipeline. The BW/RC pipeline is configured to write an incoming flit to an input buffer(s) of a start EXTRA router and compute the route for the incoming head flit by selecting an output port to depart from the start EXTRA router. The SA-L pipeline is configured to arbitrate the start EXTRA router to choose an input port and an output port for a winning flit. The SR pipeline is configured to handle the transmission of a number of SR signals from the start EXTRA router to downstream EXTRA routers.
