  • Patent number: 12625515
    Abstract: Various systems and methods for evaluating time synchronization values provided from a clock leader are discussed. An example method performed by a clock follower device includes: obtaining a timestamp from a time synchronization protocol that provides synchronized time values from a clock leader; determining, based on the timestamp, a measured time drift value that represents a time drift of a hardware clock, with the time drift observed relative to the clock leader; determining an estimated time drift value that models a time drift of the hardware clock, modeled from one or more environmental conditions experienced by the hardware clock; comparing the measured time drift value with the estimated time drift value; and adjusting a clock of the device based on the timestamp, in response to validating that the measured time drift value is within a statistically expected range corresponding to the estimated time drift value.

  • Patent number: 12513158
    Abstract: Techniques include an apparatus to retrieve a first parameter for the IDS to monitor a device for a time-synchronized network. The first parameter may represent a number of messages the IDS needs to analyze in order to detect a security attack. The messages may comprise time information to synchronize a clock for a device to a network time for a time-synchronized network. The processor circuitry may retrieve a second parameter for a time sensitive application. The second parameter may represent a defined amount of time error tolerated by the time sensitive application, and determine a third parameter for the IDS based on the first and second parameters. The third parameter may represent a defined frequency to receive a number of messages with time information in order to detect the security attack on the device within a defined time interval. Other embodiments are described and claimed.
