1. An encoder comprising:
a first generator configured for generating a first hash value based on first input data;
a first exclusive OR (XOR) operator configured for performing a first XOR operation between second input data and a cryptographic value to generate a first operation value;
a second XOR operator configured for performing a second XOR operation between the first hash value and the first operation value to generate a second operation value;
a second generator configured for generating a second hash value based on the first operation value; and
an encoding component configured for encoding the first input data, the second operation value and the second hash value to output first to third encoded data.
