Systems and techniques for policy-based access control in content networks are herein described. Content and metadata describing the content may be encrypted by using an access control policy and a cryptographic key associated with the access control policy. The access control policy may be defined with a set of access control attributes. Each node in the content-based network may be assigned a set of access control attributes and a cryptographic key generated as a function of its assigned set of access control attributes. Each node in the content-based network may be configured to decrypt successfully the metadata or the content if and only if the assigned set of access control attributes of the node satisfies the access control policy used to encrypt the metadata or content.
