Abstract

Data compression has been playing an important role in the areas of data transmission. Many great contributions have been made in this area, such as Huffman coding, LZW algorithm, run length coding, and so on. These methods only focus on the data compression. On the other hand, it is very important for us to encrypt our data to against malicious theft and attack during transmission. A novel algorithm named Swapped Huffman code Table (SHT algorithm) which joints compression and encryption based on the Huffman coding is proposed in this paper. This algorithm is a enhanced Huffman coding with encryption for wireless data broadcasting system. The application example and evaluation results show its feasibility and efficiency.
