Abstract
Techniques are described herein that are capable of establishing an internal clock value of an IoT device based at least on a timestamp received from a security service via a secure connection. The IoT device is booted up by setting a time value associated with an internal clock of the IoT device to a default time value. The time value is reset to an updated time value that is received from a trusted time source. A secure connection is established between the IoT device and the security service using the updated time value. A first timestamp is received by the IoT device from the security service via the secure connection. The time value is reset to a second updated time value that is based at least on the first timestamp. An operation that utilizes a second timestamp, which is based at least on the second updated time value, is performed.
