“…to Base Station Controller -managing all BTSs in the subsystem -or Mobile Services Switching Centre -fixed portion of a GSM network interfacing with the Radio subsystem and connecting other MSCs and to several geographically clustered BSCs) there is no more encryption involved [11]. Thereafter, SMS data travels in plain text [5]. For this reason, entities might be adamant about adopting this channel over which to transact sensitive information.…”

the provision of sensitive information over SMS has been held back due to the inherent privacy problems of SMS. Sending messages as plain-text carries multiple risks. SMS encryption is one solution to this problem. However software written for specific devices might affect the User Experience (UX) while impacting existing investments. Also, using the phone's memory as a data store provides no guarantees against intrusion attacks. A standards-based STK (SIM Toolkit) application has been adopted in order to strike a balance between usability and mobility. An 8-bit microcontroller was used as the main platform for this security application, implementing Twofish symmetric encryption to enhance privacy and confidentiality. Creating synergy between Security and Usability is a challenge, and this paper discusses the role of STK and SMS in G2B m-Government.

“…Luckily, some of the problems related to GSM are partly solved by the authors of [7] based on the Universal Mobile Telecommunication System (UMTS), while other problems remain unsolved. In [8] the authors presented that there is some kind of unauthorized access to the information within the database of the mobile centers and the clients' devices. The building of the other security layer and basic mobile construction progresses due to the security focus.…”

Recently, the usage of mobile phones around the world is growing more and more. Short Message Service (SMS) is one of the most important applications due to its easy way to send and receive messages from users to users. There have been many transmission protocols aiming to make sure secure and effective transferring in the SMS. Some of them are based on symmetric algorithms, while others are based on signature encryption or public key infrastructure. However, all of these existing protocols lack sufficient security or high efficiency. When the protocols possess high security margin, they usually have a limited performance in software. And when the performance is guaranteed, the security margin usually decreases. So in this paper, we study the advantages and disadvantages of some widely-used protocols. Basing on this, we propose a new protocol for secure SMS transmission. Our protocol improves both the structure and the modules of previous protocols from theoretical and practical aspects, so that it can assure the security level as well as very efficient performance. Compared with other protocols having similar security, our protocol has a more convenient implementation. Compared with other protocols with similar performance, our protocol is safer. Also, we use a signature model which does not need the PKI on-line, increasing the security greatly. Finally, we take experiments on real mobile phones to verify our protocol and analyze the results
