Abstract

Presently, mobile handheld device successfully replaces traditional telephone to become the most popular wireless communication tools. Mobile Short Message Service (SMS) and Multimedia Message Service (MMS) fulfill almost all the user requirements as an effective communication and information delivering service. Since SMS/MMS become so popular on daily communication, there is a demand to communicate or exchange confidential information in a secure environment. Public Key Infrastructure (PKI) is a proven solution, which using pairing of key, for secure communication encryption. In this thesis, M-PKI is introduced to provide PKI encryption to the mobile SMS. A new approach is proposed in order to develop an application that allows the enduser to send private and classified message via SMS. M-PKI classifies the message into three categories which are normal SMS, internal SMS, and confidential SMS. This classification is specially designed to meet various user requirements on the level of security and performance. The usage, performance, and security strength of M-PKI messaging in performing encryption and decryption process are tested on selected javaenabled mobile phone. The size of pairing of key is studied and decided by the tradeoff between performance and security. The key pair generation and distribution are done by the M CA (M-PKI Certificate Authority).
