    Abstract: Techniques to secure a time sensitive network are described. An apparatus may establish a data stream between a first device and a second device in a network domain, the network domain includes a plurality of switching nodes, receive messages from the first device by the second device in the network domain, the messages to comprise time information to synchronize a first clock for the first device and a second clock for the second device to a network time for the network domain, update a correction field for a received message with a residence time and time delay value by the second device, determine whether the updated message is benign or malicious, update the correction field for the updated message with an inference time when the updated message is benign, and prevent relay of the updated message to other devices in the network domain when the updated message is malicious.

    Abstract: Techniques include receiving a message with time information at an ingress queue for an ingress interface of an intrusion detection system (IDS), the IDS to monitor a network node of a time-synchronized network (TSN), generating an entrance timestamp for the message, the entrance timestamp to comprise a time value representing when the message is received at the ingress queue of the ingress interface of the IDS, inspecting the message for indications of a security attack by the IDS, generating an exit timestamp for the message, the exit timestamp to comprise a time value representing when the message is received at an egress queue of an egress interface of the IDS, and generating an inspection time interval associated with the IDS, the inspection time interval to represent a time interval between the entrance timestamp and the exit timestamp for the message while transiting the IDS. Other embodiments are described and claimed.

    Abstract: A method comprises receiving an image of an update for a software module, a rate parameter, an index parameter, and a public key, generating a 32-byte aligned string, computing a state parameter using the 32-byte aligned string, generating a modified message representative, computing a Merkle Tree root node, and in response to a determination that the Merkle Tree root node matches the public key, forwarding, to a remote device, the image of the update for a software module, the state parameter; and the modified message representative.
