Secure deterministic fabric for safe and secure product design

摘要

A secure deterministic fabric includes switches that segregate data traffic requiring disparate levels of authentication or having different safety levels. Data may be segregated physically, utilizing different hardware; or virtually, by allocating certain assets such as memory blocks exclusively for certain levels of authentication. The secure deterministic fabric may include elements for safety monitoring and multi-level security monitoring.

主权项

1. An apparatus for routing data traffic comprising:
a first fabric switch; a second fabric switch; and a plurality of processing elements connected to the first fabric switch and the second fabric switch, each of the plurality of processing elements configured to authenticate security credentials associated with each of the first fabric switch and the second fabric switch, wherein:
the first fabric switch is configured to exclusively route data having a first security level;the second fabric switch is configured to exclusively route data having a second security level;the first fabric switch is physically separated from the second fabric switch; anda first processing element in the plurality of processing elements is configured to authenticate data traffic directed toward a second processing element in the plurality of processing elements when the second processing element fails.
