Abstract: Technology for a user interface that supports an access control mechanism for network sharing. An example method involves providing a user interface comprising media items and media availability indicators, wherein a media availability indicator indicates one or more states of a media item; updating the media availability indicator to represent that an encrypted version of the media item and a wrapped key have been received over a connection, wherein the wrapped key was encrypted using a public key of a server; enabling the user interface to initiate the transmission of the wrapped key to the server, wherein the wrapped key comprises a cryptographic key for the encrypted version of the media item; receiving the cryptographic key that is unwrapped by the server using a private key of the server; and updating the media availability indicator of the user interface to represent the media item is available to be experienced.

Abstract: Implementations disclose an access control mechanism for peer-to-peer sharing technology. A method includes receiving, by a processing device of a first user device, an encrypted media item and a wrapped key from a second user device, wherein the wrapped key comprises content masked from the first user device; transmitting, by the first user device, the wrapped key and a request to a media server to determine whether the first user device is authorized to play the encrypted media item; receiving, from the media server, a response indicating the first user device is authorized to play the encrypted media item, the response comprising a cryptographic key derived from the wrapped key; and decrypting the encrypted media item using the cryptographic key.
