Abstract

A method and apparatus for securely communicating ephemeral information from a first node (160) to a second node (162). In a first embodiment, the first node (160) encodes and transmits to the second node (162) an ephemeral message that is encrypted, at least in part, with an ephemeral key. Only the Second node (162) has the information needed by an ephmeral key server (164) to acheive decryption of the payload information included in the message sento it from the first node (160).
