An apparatus, system, and method are directed towards parsing and selectively encrypting different portions of data in real-time, decrypting the encrypted data in real-time, and passing the data to a media player on a client computer or other network capable device. Data in a network packet may be parsed into payload and non-payload portions. The payload portion of the packet data may then be examined to determine whether a predefined type of the data is recognized. For example, in one embodiment, the predefined data type may be media content. If the payload portion is recognized as a predefined data type, then it may be selectively encrypted. The selectively encrypted payload portion and non-payload portion of the packet may then be combined, such that the non-payload portion may be employed by firewalls, proxies, and/or NATs to route the packet towards the client computer or other network capable device.

Selectively encrypting different portions of data sent over a network

An apparatus and method for selectively encrypting portions of data sent over a network between a server and a client. The apparatus includes parsing means for separating a first portion of the data from a second portion of the data, encrypting means for encrypting only of the first portion of the data, and combining means for combining the encrypted first portion of the data with the second portion of the data, wherein the second portion of the data is not encrypted. The apparatus further includes decrypting means installed at the client for decrypting the encrypted portion of the data. The apparatus is platform independent in terms of media format and data protocol. The encryption unit encrypts data transparently to the client based on the media format. The apparatus of the invention is implemented as one of an application and a plug-in object. The method for selectively encrypting portions of data which differ from each other in at least on characteristic sent over a network between a server and a client includes parsing the data into a first and second portion, encrypting only the first portion of the data, and sending the encrypted first portion and the second portion of the data over the network to the client. The method further includes receiving data from the server, determining whether a data stream is established between the server and the client, and negotiating an encryption key with a decryption shim of the client.
