Cross enterprise communication

摘要

A system enables intermediary communication components to carry out cross enterprise communication. At a first sending enterprise the system comprises: a processor executing code to: receive a signed encrypted message from a sender within a first enterprise; validate the sender; decrypt the message; encrypt the message for receipt by a second enterprise; sign the encrypted message by the first enterprise; and send the re-signed re-encrypted message to a second enterprise. At the second receiving enterprise, the system comprises a processor executing code to: receive a signed encrypted message from a first enterprise; validate that the first enterprise is the sender; decrypt the message; encrypt the message for receipt by recipients at the second enterprise; sign the encrypted message by the second enterprise indicating that the message is from the first enterprise; and send the re-signed re-encrypted message to the recipients of the second enterprise.
