Abstract

See full text

Systems, methods, and computer-readable media for generating a keystream using media data and using the keystream to encrypt and decrypt messages are described herein. The keystream may be generated independently and at least partially in parallel by both a sender and a receiver of a message. The sender may use its independently generated keystream to encrypt a message and a receiver may use its independently generated keystream to decrypt the message. Both the sender and receiver may utilize the same algorithm for generating their respective keystreams, thereby ensuring that the same keystream is generated by both sender and receiver. The sender may share a session key with a receiver using an asymmetric encryption technique. The session key may contain a collection of subkeys. Both the sender and the receiver may independently determine media database indices that match the subkeys and aggregate the corresponding media data streams to obtain the keystream.
