“…3 we can see that with 4-Sets-CutDecoding algorithm#3 we have succeeded to eliminate a larger number of null-errors (for p ≥ 0.04, PER c4.3 is from 1.2 to 5.2 times smaller than PER c4.2 ), again without decreasing of the decoding speed. And with the last modification, i.e., 4-Sets-Cut-Decoding algorithm#4, for p > 0.05 we have obtained better results for packeterror probabilities with almost the same decoding speed.…”

“…Then two algorithms are used, one for error-correcting codes and another for obtaining information security. In order to obtain more efficient design, in the paper [3] authors give one algorithm where a block cipher and an error-correcting code are combined. The main application of their design is for cryptographic purposes, although it can be used as an error-correcting code.…”

In this paper, secure channel coding schemes based on convolutional codes are suggested to enhance the performance of combined cryptography and coding theory, which is called "Crypto-Coding". In the proposed work, Data Encryption Standard (DES) for security and channel coding algorithm such as convolutional code for efficient transmission are combined in a mono-block. This modification is required to improve the overall system performance. The combined System's performances are evaluated on Land Mobile Satellite (LMS) Channel. The results are compared with the system using ideal encryption and decryption.

“…This can be done by using a new class of codes that we call the high diffusion code (HDcodes) [13] at the diffusion layer. Although, these codes were designed with the specific goal of constructing error correcting ciphers [14], these can also be used for our purposes since the codes provide a means of securely increasing the encryption throughput. Note that, in [14] we first introduced the HDcipher in the electronic codebook (ECB) mode and present a proof-of-concept construction using a specific construction in GF (8).…”

In this mode (and the cipher block chaining mode) the primary function of the HD-cipher is to correct transmission errors.…”

The current encryption standard for wireless networks recommend using the AES cipher in the counter (CTR) mode for confidentiality and in the cipher block chaining (CBC) mode for authentication. In the counter mode, a 128 bit counter is encrypted using the AES into 128 bit keystream which is then XORed with 128 bits of plaintext before transmission. This operation is repeated for the entire frame and results in heavy energy consumption for larger frames. In this paper, we propose a novel cipher called High Diffusion (HD) cipher that securely expands a given 128 bit counter value to a larger 288 bit keystream during encryption, thus reducing the number of encryptions per frame compared to the AES. We show that the HD cipher is as secure as the AES under differential, linear cryptanalysis and the Square attack. Using an experimental set up consisting of a laptop with 1.8 GHz Pentium 4 processor and an Intrinsyc CerfCube with 233 MHz ARM processor we measure the energy consumption of both the AES and the HD cipher encryption operation. We observe that using HD cipher instead of AES for encryption will result in about 40% saving in energy consumption on both the laptop and the CerfCube. We also observe that energy efficiency due to HD cipher is significant for larger frame lengths.
