Broadcast Encryption

Broadcast encryption is an interesting application of cryptography which allows one to broadcast a secret to a changing group of intended recipients in such a way that no one outside this group can view the secret. Interest in using broadcast encryption techniques has grown considerably in recent years and such techniques have been in- tegrated in many applications and technologies such as virtual private networks, cable TV networks, mobile and wireless networks and many more. This report describes broadcast encryption in depth along with the related techniques, threats, protocols and applications.
