Increasing Messenger service capability and security on mobile devices using Hybrid Compression-HR2 algorithm

Messenger service, such as SMS and Whatsapp, was considered as insecure service in a mobile device and has a potential to be used by man in the middle attack. To increase Messeger service capability and security, the Huffman compression method is used to shorten character followed by the security algorithms which is the combination of RSA and ROT13. The Messages will be processed by compressed the text using Huffman compression then rotated 13 characters and encrypted using the RSA algorithm with the addition of the values in the ASCII value per looping character (Hybrid Compression-HR2 algorithm). This approach is considered a secured approach as the same text/char acters in the different block, will produce different encrypted and compressed text. This approach is also unique which offer better protection in concise message length.
