Abstract: A data guard circuit can be used to verify encryption of the data traffic on a bus between two integrated circuit (IC) devices. The data guard circuit can monitor the data traffic on the bus to analyze the data traffic based on a configuration. The analysis can be performed by sampling the data traffic, and a statistical data pattern can be identified in the sampled data traffic. The statistical data pattern can be compared with a threshold to determine whether the data traffic is encrypted. The data guard circuit can generate a notification if the data traffic is not encrypted as expected so that an appropriate action can be taken to protect the data.

Abstract: Various embodiments of apparatuses and methods for multi-cast, multiple unicast, and unicast distribution of messages with time synchronized delivery are described. In some embodiments, the disclosed system and methods include a reference timekeeper providing a reference clock to one or more host computing devices.

Each isolated timing hardware provides either the packet, or information to access the packet, to its respective destination compute instance subsequent to determining that the same specified time to deliver the packet has occurred. Thus, the respective packets are delivered near simultaneously to the one or more destination compute instances.
