Abstract
A substitute box includes a target input terminal, an obfuscation input terminal, a first output terminal and a second output terminal. The target input terminal is configured to receive a target input data. The obfuscation input terminal is configured to receive an obfuscation input data unrelated to a plaintext. The first output terminal is configured to output a first output data. The second output terminal is configured to output a second output data associated with the first output data. The first output data and the second output data are generated according to both the target input data and the obfuscation input data.
