Chapter 2: GSM security issues Literature review 2. Chapter 3: The focus of study 3. GSM systems are vulnerable to an unauthorized access and eavesdroppings when compared with the traditional fixed wired networks due to the mobility of its users. The main idea of this project is to develop an application device to secure mobile banking over unsecure GSM network. It is important to mention here that, mobile banking is a term used for performing balance checks, account transactions, payments, credit applications and many other online applications. But unfortunately, the security architecture for cellular network is not entirely secure.

Some of these services have possible security vulnerabilities. This paper investigates the security measures used in GSM networks which include Authentication, Encryption, Equipment Identification and Subscriber Identity Confidentiality, as well as the manifestation of network vulnerabilities including SIM, SMS attacks, encryption and signaling attacks. Suggestions on mitigative measness are also discussed. The Information Manager Vol.


These nodes are involved to encrypt/decrypt the data and authenticate the user (​MS) in GSM, GPRS and UMTS. To provide security services like authentication.

State of the Art in Applied Cryptography pp Cite as. Security requirements and services of a mobile communication system differ, due to the radio communication between the user and the base station, extensively from those of a fixed network. Eavesdropping on the radio path, intercepting data or tracing the whereabouts of a user by listening to signalling data are other serious threats. Unable to display preview. Download preview PDF.

GSM - Security and Encryption

Navigation menu

GSM is the most secured cellular telecommunications system available today. GSM has its security methods standardized. GSM maintains end-to-end security by retaining the confidentiality of calls and anonymity of the GSM subscriber. The privacy of the communication is maintained by applying encryption algorithms and frequency hopping that can be enabled using digital systems and signalling. The GSM network authenticates the identity of the subscriber through the use of a challenge-response mechanism. If the values do not match, the connection is terminated and an authentication failure is indicated to the MS. The calculation of the signed response is processed within the SIM.

Несмотря на солидный заработок, Танкадо ездил на службу на стареньком мопеде и обедал в одиночестве за своим рабочим столом, вместо того чтобы вместе с сослуживцами поглощать котлеты из телятины и луковый суп с картофелем - фирменные блюда местной столовой. Энсей пользовался всеобщим уважением, работал творчески, с блеском, что дано немногим. Он был добрым и честным, выдержанным и безукоризненным в общении. Самым главным для него была моральная чистота. Именно по этой причине увольнение из АН Б и последующая депортация стали для него таким шоком. Танкадо, как и остальные сотрудники шифровалки, работал над проектом ТРАНСТЕКСТА, будучи уверенным, что в случае успеха эта машина будет использоваться для расшифровки электронной почты только с санкции министерства юстиции.

Вопросы, не имеющие ответов, множились в голове. А теперь все по порядку, - произнесла она вслух. К Хейлу можно вернуться чуть позже. Сосредоточившись, Сьюзан перезагрузила Следопыта и нажала клавишу ВВОД. Терминал пискнул.
