Abstract
Described herein are methods, systems, and software for encrypting and erasing data objects in a content node. In one example, a method of operating a content node that caches content divided into one or more data objects includes encrypting the one or more data objects using separate encryption keys for each of the one or more data objects, the separate encryption keys comprising a common portion shared by the one or more data objects and an individualized portion unique to each data object. The method further provides receiving a purge request to erase at least one data object and, responsive to the purge request, erasing at least one of the common portion or the individualized portion for the at least one data object based on the purge request.
