Mobile Instant Messenger is an IM application that need communication fastly and in a secured manner. A good level security with strong autentication must be applied to ensure data transmission between IM sender and IM recipient over public network is valid. This paper propose a new method for securing message IM with an efficient autentication method. In this research, an efficient autentication method will implement Hyper Elliptic Curve Cryptosystem (HECC) algorithm in generating and verifiying the message sign while occur data transaction. The main function of signing message is to autenticate data to ensure validation of data. Then, the sign method used to ensure unauthorized person cannot change the original data or information that sent through the network. This method developed to give auntentication user with key pair per session and using it while communication running between sender and receiver. It is a novel approach in IM auntentication method to elevate the security level of data.
