Abstract
An apparatus includes a network interface that receives a CDN token key and transmits event data including a content ID that identifies content within a webcast or a virtual event. The apparatus also includes a processor that generates a message authentication code, at least in part based on the content ID and the CDN token key. The event data identifies the message authentication code, and the network interface transmits the content.
