Security Enhanced Symmetric Key Encryption Employing an Integer Code for the Erasure Channel

An instance of the framework for cryptographic security enhancement symmetric-key encryption employing a dedicated error correction encoding is addressed. The main components proposal are: (i) coding and (ii) use simulator noisy channel. proposed designed binary erasure channel where at most one bit erased in each codeword byte. has been evaluated traditional scenario we consider advantage an attacker to correctly decide which two known messages given ciphertext corresponds. evaluation shows that provides reduction considered attacker’s comparison with initial setting. implementation complexity considered, it implies suitable trade-off between increased complexity.
