encryption

To ensure replay protection, it includes a packet number into tow efficient contributions: AES block cipher algorithm with a 128-bit encryption key and Counter Mode with CBC mode [21], [22].

In the beginning, Alice computes word length from the plaintext and executes modulus 2 operation if she wants to encrypt plaintext with (2 * 2) matrix in accordance with the Hill cipher algorithm [1].

CipherCraft is a cipher engine that supports the cipher algorithm Camellia and PSEC-KEM.
