Crypto-Coding as DES-Convolution for Land Mobile Satellite Channel
Rajashri Khanai, G. H. Kulkarni · International Journal of Computer Applications · 2014
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.
