This article presents an overview of security issues for mobile and wireless communications. It describes the security requirements and architectural options for these networks. Subsequently three technologies are discussed in more detail: mobile phones (GSM and 3GSM), Wireless LAN (IEEE 802.11) and Personal Area Networks (Bluetooth). A critical evaluation is given of the strengths and weakness...

Background: The rapidly increasing use of mobile phones has led to public concerns about possible health effects of these popular communication devices. This study is an attempt to investigate the effects of radiofrequency (RF) radiation produced by GSM mobile phones on the insulin release in rats.Methods: Forty two female adult Sprague Dawley rats were randomly divided into 4 groups. Group1 we...

Background:As the use of mobile phones is increasing, public concern about the harmful effects of radiation emitted by these devices is also growing. In addition, protection questions and biological effects are among growing concerns which have remained largely unanswered. Stem cells are useful models to assess the effects of radiofrequency electromagnetic fields (RF-EMF) on other cell lines. S...

The most widely used mobile computing device today is the Mobile phone, can be used not only for voice and data communications but also as a computing device running context aware applications. In this paper we present a model that based on GSM data base. The objective of this paper identifies user groups based on places visited by a user, date, time, longitude and latitude. This information ca...

In this paper an attempt is made to extend the capability of mobile phones for secure control of remote electrical devices using SMS services. The transmission of SMS in GSM network is not secure. It only provides the encryption between Mobile Station to Base Station Controller. The message transmitted between GSM operator networks is not encrypted and hence is not safe. Mobile SMS service has ...

This paper describes, to monitor the signals of ECG, body temperature, heart rate are measured and given to ARM controller. Through GSM/GPRS modem updated parameters are sending directly to the doctor’s mobile phone/nearby hospital web portal doctor can also query about the human health through GSM by SMS. In addition to that if elderly people need to operate any electrical devices, can help th...

GSM is the most popular standard for mobile phones in the world. In spite of the tremendous market growth, however, the GSM system has the fatal security problems in TMSI allocation protocol. These problems are right user authentication and location privacy. In this paper, we propose the secure TMSI allocation mechanism using the certification concept to solve these problems. The proposed mecha...

BACKGROUND There are about 1.6 billion GSM cellular phones in use throughout the world today. Numerous papers have reported various biological effects in humans exposed to electromagnetic fields emitted by mobile phones. The aim of the present study was to advance our understanding of potential adverse effects of the GSM mobile phones on the human hearing system. METHODS Auditory Brainstem Re...

The ascending number of mobile devices is accompanied by an ever increasing effort of malware developers to find new means of infecting them. GSM, as a basic technology for mobile communication used by most mobile phones, lacks certain security aspects. In order to access a provider network the mobile equipment authenticates itself against the network, whereas the latter does not have to prove ...

Mobile phones and stethoscopes used in neonatology units could be colonized by potentiel bacteria pathogens. It can be a vector of severe nosocomial infections and multi-drug-resistant pathogens. The aim of this study is to evaluate the microbial contamination of mobile phones and stethoscopes, used by medical and paramedical staff. The study was conducted in neonatal intensive care unit (NICU)...
