METHOD FOR PROTECTING THE SECURITY OF THE IDENTIFICATION OF THE SENDER OF MESSAGES TRANSMITTED BY PROMISED CHANNELS

摘要

abstract “method for protecting the sender identification of messages transmitted by promiscuous channels” The method allows a sender to protect his identification in messages sent to a recipient. Even if promiscuous channels are used for message transmission, only the recipient is able to reveal the sender's identity. The method uses symmetric encryption of low computational requirements, without relying on a unique shared key between the participants, so that a sender cannot reveal the identity of the others. The method gradually protects sender identification (106) using successive symmetric cryptographic operations (305) and keys from a binary tree structure constructed for this purpose on the recipient, which applies the steps in reverse of the protection of the sender. sender to reveal your identification. It is also possible to encrypt the message body. 1/1
