Abstract
In one embodiment, a method of secure network transmission is performed by a computer system. The method includes encrypting a payload via a first symmetric key and encrypting the first symmetric key via a second symmetric key. The method further includes encrypting an author header comprising the encrypted first symmetric key and a recipient list via a third symmetric key, wherein the recipient list comprises at least one recipient. The method also includes encrypting the third symmetric key via a public asymmetric key associated with an authentication server. Furthermore, the method includes transmitting the encrypted author header and the encrypted third symmetric key to the authentication server for use in recipient-initiated pre-access authentication. In addition, the method includes transmitting the encrypted payload and the second symmetric key over a computer network to the at least one recipient.
