Authenticated access to cacheable sensor information in information centric data network

An apparatus comprising:

• a device interface circuit configured for receiving, 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;
• a clock circuit configured for generating a current device timestamp value;
• and
• a processor circuit is configured for generating the secured request based on generating a reduced-resolution time value by dividing the current device timestamp value by the prescribed update time interval value, and encrypting the reduced-resolution time value using the shared encryption key;
• the device interface circuit further configured for outputting 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.

One or more non-transitory tangible media encoded with logic for execution by a machine and when executed by the machine operable for:

• receiving, by the machine implemented as 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.

A method comprising:

• receiving, by a content supplier device in a data network, a secured request for a data object, the secured request including an object name identifying the data object and an encrypted portion;
• decrypting the encrypted portion into a decrypted value using an encryption key stored by the content supplier device and associated with the data object;
• and
• selectively authenticating the secured request in response to determining the decrypted value, multiplied by a prescribed update time interval value associated with the data object, substantially matches a current device timestamp of the content supplier device.
