Channel Coding as a Cryptography Enhancer
نویسندگان
چکیده
In this work, channel decoding is considered as a promising way for improvement of cryptographic functions. Use of MAC/H-MAC values and digital signatures is analyzed in a context of code concatenation, together with convolutional codes using MAP decoding algorithm. Soft Input Decryption method, which uses L-values from channel decoder, presents an efficient method for integrating cryptography into decoding. The results of computer simulations that implement this method have been also presented. Additionally, the number of L-values verifications has been tested and compared with the theoretical results. Key-Words: Soft Input Decryption, Code Concatenation, L-values, MAC/H-MAC, MAP, Channel Decoding, Turbo Decoding, CCER, CRC 1 Cryptography as the Part of Decoding

An efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
