The implementation relies on a hardware crypto accelerator with 4×10-bit ARM® Cortex-MX7 processor cores on a high-end computer running Linux 2.6 (with ARMv7 architecture). Parameters: cipher_key = 8 -byte key, key_Len = 13, encryption_mode = CBC, encryption_mode_ID_mask = 4 (6, 7, 8, 9) encryption_mode_also = RC4-MD5, encryption_mode_block_cipher = 1, encryption_ mode_block_plaintext = 1, padding = 1, key_length = 17, padding_length = 11 Description: In this paper we explain in detail each element (encryption, decryption, encryption_mode_block_cipher) and give a very practical example in the context of stream ciphers. In the next sections, we describe further technical details of the Hermes8F-80 cipher, then look at a proof-of-concept implementation of the stream cipher with 8-byte key, then we discuss the use of Hermes8F-128 cipher in the context of block ciphers. We conclude with a discussion of stream ciphers themselves. KEYWORDS: stream cipher, low-complexity stream cipher, AES, RESULTS, CBC, block cipher, CBC mode, block ciphers, low-complexity algorithm, encryption, encryption_mode-block_cipher, encryption_mode
