Abstract

SMS or Short Message Service is a short messaging service via mobile phone. Although it is part of the first phase of the GSM standard capabilities, SMS is still a service that is widely used by many people. Generally, SMS does not guarantee the confidentiality and integrity of messages that sent by the user. Therefore the text messages that sent by the user is the confidential and private message, so confidentiality message is very important, to be taken care from people who are not eligible. And so we need a security system in conveying the message. Message encryption and decryption application can increase the security level of the service that requires confidentiality of messages. This can reduce the leakage of information to the parties that not concerned, like mobile phone service (operator). To enhance security in encryption and decryption application SMS messages, it is necessary to use a reliable algorithm. ECC (Elliptic Curve Cryptography) is an alternative encryption method that can be used to maintain the confidentiality of SMS services. This method allows the encryption of the message, from sender's mobile phone to recipient mobile phone. By utilizing this method, the SMS service can be more secure because the encryption algorithms used are strong enough and the key that is used is difficult to solve. This algorithm is a public key algorithm, will be safer when compared with the private key algorithm. In this application, the system combines the ECC algorithm with private key algorithm, in order to obtain maximum results. This application is also equipped with a compression to reduce swelling number of characters from encryption. Compression method used is the Huffman method.
