Abstract
A technique to cache content securely within edge network environments, even within portions of that network that might be considered less secure than what a customer desires, while still providing the acceleration and off-loading benefits of the edge network. The approach ensures that customer confidential data (whether content, keys, etc.) are not exposed either in transit or at rest. In this approach, only encrypted copies of the customer's content objects are maintained within the portion of the edge network, but without any need to manage the encryption keys. To take full advantage of the secure content caching technique, preferably the encrypted content (or portions thereof) are pre-positioned within the edge network portion to improve performance of secure content delivery from the environment.
