Personal information stored in mobile devices can be unexpectedly exposed to others when users make use of mobile banking, Internet shopping and etc.Because of the important personal information that can be easily exposed in the mobile environment, it becomes more important to have a reliable security system.It is strongly required for this mobile security system to have a small memory size and a high processing speed as its components' characteristics.Considering these characteristics of the mobile security system, this paper aims at proposing a public key generation and an encryption mechanism that generates a hidden key using the Newton-Raphson method and applies the Diffie-Hellman key-exchange method to authenticate the peer.This mechanism uses an elliptic curve resulting in a small size of encryption key and a high security level.
