Abstract

By analyzing a content of a first message, a confidentiality level of the first message is determined. An encryption rule for a first computational complexity level corresponding to the confidentiality level of the first message is selected. The first message is encoded according to the encryption rule. The encoded first message and the confidentiality level of the first message are caused to be sent to a recipient.
