    摘要： In one embodiment, a method comprises: receiving, by a requestor device in a data network, authentication request parameters for generating a secured request for a data object, the authentication request parameters comprising a shared encryption key and a prescribed update time interval value; generating, by the requestor device, the secured request based on generating a reduced-resolution time value by dividing a current device timestamp value of the requestor device by the prescribed update time interval value, and encrypting the reduced-resolution time value using the shared encryption key; and outputting, by the requestor device, the secured request specifying an object name identifying the data object and the encrypted reduced-resolution time value, enabling a content supplier device to authenticate the secured request based on determining whether the reduced-resolution time value, multiplied by the prescribed update time interval, substantially matches a corresponding timestamp value of the content supplier device.
