Abstract
An apparatus includes a storage, a network interface, and a processor. The storage is to store content within a webcast or a virtual event. The network interface transmits a CDN token key and receives a client content request including a content hash and a message authentication code. The processor performs a decryption of the message authentication code, at least in part based on the CDN token key, and performs a reverse hash on the content hash to obtain a content ID that identifies the content. The network interface transmits the content, at least in part based on the content ID.
