Abstract
A hardware cryptographic engine for encrypting transmission data may include a plurality of ciphertext engines that generate intermediate ciphertexts and final ciphertexts. At least one of the ciphertext engines may receive an intermediate ciphertext output from at least one neighboring ciphertext engine to generate a corresponding intermediate ciphertext and final ciphertext. A method of encrypting transmission data may include inputting a second intermediate ciphertext of a second ciphertext engine to a first ciphertext engine and generating a first intermediate ciphertext of the first ciphertext engine using the second intermediate ciphertext.
