EEE-GSM: End-to-End Encryption Scheme over GSM System

Providing End-to-end Secure Communicationsin Gsm Networks

The broadcast nature of radio medium in GSM networks makes them more vulnerable to various attacks. Any attacker can have complete control over the communication channel, listen to phone calls, read email, and spy on whatever data has been sent via GSM mobile communication system. This paper introduces a middleware security system that aims to protect the GSM communication channel and minimize ...

Cryptanalysis of GSM encryption algorithm A5/1

The A5/1 algorithm is one of the most famous stream cipher algorithms used for over-the-air communication privacy in GSM. The purpose of this paper is to analyze several weaknesses of A5/1, including an improvement to an attack and investigation of the A5/1 state transition. Biham and Dunkelman proposed an attack on A5/1 with a time and data complexity of 239.91and 221.1, ...

Secure Communication System over a GSM Network

As standard GSM protection methods are now well-known to be insecure, we have designed a new secure communication system over GSM network which is developed using the Symbian OS platform. It uses standard cryptographic methods such as key generators, key exchange protocols and public and private key cipher algorithms. This system allows communicating text, voice and any kind of data securely ov...

A GSM Based Localization Scheme

Wireless localization has been an active research area over the last decade due to its endless applications. In this paper, we investigate received signal strength (RSS) based estimation of a mobile station’s location, through monitoring the RSS at multiple reference software defined radio (SDR) receivers. Uplink transmission power of the mobile stations and path loss exponent are assumed to be...
