Abstract

S'MS (Short Message Service) is one 0/ Instant Messaging (1M) which is cheap, simple and easy to be used, that's why SMS can be used by people from every economy class. One of weakness in SMS is its insecurity. Encryption and compression are two alternative options that can be used to make secure the contents o[ the sent messages in different ways. Encryption camouflage contents vf message by substitution, permutation, expansion, and blocking, whereas compression hide the contents o/message by compressing it. The objective o/this research is to make double protection in sending SMS with side benefit to reduce fhe cost o[ sending SMS. Caesar algorithm and custom byte manipulation are being used lor encryption, whereas huffman, LZW, and shannon lano algorithm are three optional algorithm for compression method The result show thai encryption and compression could be implemented in SMS. It bring out an encrypted and compressed message which gives double protection in contents of SMS.
