“…However, this attack can be avoided simply by widening the circle of guessing, making the attacker take more time to find a way to access. Therefore, the higher encryption scheme with a large key size (32,64,128,168-bit,……) needs more time, maybe hours or days. Informing that, although back in the history the export rules in the United States limited key lengths to 56-bit symmetric keys, with rising the key size, resources required for a brute-force attack expand exponentially, not linearly.…”

The polar code is a unique coding approach that can achieve Shannon's capacity in modern communication systems' discrete memory-less channels with superior reliability, but it is not secure enough under modern attacks for such systems. This study aims to offer a comprehensive secured polar coding scheme that uses a combination of polar coding and the Mersenne-Twister pseudo-random number generator (MT-PRNG) to achieve a super secured encoding. The pre-shared crypto-system cyphering key initiates the starting state of the MT-PRNG as a seed. The randomly generated sequences govern the values of the frozen bits in polarized bit channels and their associated indices. A half-bit-error-rate probability system performance is calculated when the encoding ciphering keys at the receiver differ by a single bit from those utilized at the transmitter. Using calculated numerical analysis, the system is shown to be secure against brute force attacks, Rao-Nam attacks, and polar code reconstruction attacks.

The latter usually relies on the applications of encryption algorithms [31], [32]. However, neither relying on the former class nor the latter class can afford further complexity increase.…”

Military robot swarm becomes more and more important for contemporary military application. In order to satisfy sophisticated application scenarios, novel communication architecture for military robot swarm has to be conceived. In this paper, we propose a multi-carrier intelligent covert satellite communication (MCICSC) architecture based on electromagnetic environment sensing technology, in where the ability of dynamically adapting the system configuration to the holistic requirements of covertness, performance, and complexity can be considerably improved. Additionally, in order to solve the carrier synchronization problem in very low signal noise ratio (SNR) for each data stream of MCICSC, polar code (PC) is incorporated into the proposed MCICSC system. With the aid of the proposed polar code-aided multi-stream parallel feedback (PAMSPF) carrier synchronization scheme, the MCICSC system is capable of realizing high-precise carrier synchronization even in very low SNR region. Moreover, in order to further decrease the complexity of our MCICSC system, we also propose a polar code-based diversity combining (PBDC) scheme, which is capable of efficiently combing all the data streams without the aid of channel state information (CSI) estimation. Numerical simulations demonstrate that for MCICSC system the performance of the PAMSPF carrier synchronization and PBDC combining schemes can get extremely close to that of an ideally synchronized system. Complexity analysis of the proposed algorithms is given as well.

Satellite broadcast communications make demand on reliable and secure data transmissions. Aiming at balancing data disorder and correlation from encryption and errors correction, this paper proposes a novel error correction and encryption algorithm combined fountain code and advanced encrypt standard (FC-AES), which constructs a 3-layer cascade framework for cryptosystem to harmonize the coding payloads of services, products, and users. Furtherly, distributed degree would be compensated with round key, which provides with entire security controls. Information degree is designed to limit data overhead and disorder. Sparsely coding control for product degree is developed to prevent decoding error avalanche. We also provide a suitable decryption scheme for FC-AES. The simulations show the new algorithm enhances the performance of data-recovery failure probability by 29.56% and average error symbol rate by 13.09%.
