The data produced in today's Internet and computer world are expanding their wings day by day. With the passage of time, storage and archiving of this data are becoming a significant problem. To overcome this problem, attempts have been made to reduce data sizes using compression methods. Therefore, compression algorithms have received great attention. In this study, two efficient encodingalgorithms are presented and explained in a crystal-clear manner. In all compression algorithms, frequency modulation is used. In this way, the characters with the highest frequency after each character are determined and the huffman encoding algorithm is applied to them. In this study, the compression ratio (CR) is 49.44%. Moreover, 30 randomly selected images in three different datasets consisting of USC-SIPI, UCID, and STARE databases have been used to evaluate the performance of the algorithms. Consequently, excellent results have been obtained in all test images according to well-known comparison algorithms such as the huffman encoding algorithm, arithmetic coding algorithm, and LPHEA.

this paper proposes a new data transmission technique that uses Quantum Key Distribution (QKD) method, One Time Pad (OTP) encryption technique and huffmanencoding compression algorithm to transmit the data more securely and efficiently. While data is transmitted, requirements like secrecy, less overhead through compression etc are crucial issues. QKD is one of the most promising methods which provide unconditional security. It relies upon the immutable laws of quantum physics rather than computational complexity as the basis of its secrecy. To establish the trust between the sender and the receiver, this paper considers a trusted center that distributes and verifies the key. Also it uses huffmanencoding-a lossless compression algorithm to compress the transmitted data over the classical channel that reduces the data transmission overhead. Moreover for data encryption, it applies OTP technique with the key randomly generated by the QKD method that ensures the secrecy of the transmitted data over the classical channel. Thus the overhead of both quantum and classical channels are reduced. Finally the time requirements for encoding-decoding and encryption-decryption for the proposed technique are evaluated.
