Abstract: Disclosed is a method for protecting message data. In the method, the message data is padded with padding bits generated based on a deterministic function performed on the message data. The padded message data is compressed to generate compressed data. A length of the compressed data is dependent on the padding bits. The compressed data is encrypted to generate encrypted message data.
