Secure Communication System over a GSM Network

摘要

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 over GSM as well as over other communication channels.
