Opis:
Assume that some businessmen wish to have a meeting. For this to occur, they usually have to meet somewhere. If they cannot meet physically, then they can take part in a video (or audio) conference to discuss whatever needs to be discussed. But what if their meeting is meant to be private? In this case they need a cryptographic protocol that allows them to exchange their ideas remotely, while keeping them secure from any potential eavesdropper. In this paper we list all the necessary requirements that a cryptographic protocol must have in order to allow several businessmen to exchange their ideas securely over the Internet. Moreover, and based on the standard taxonomy of cryptographic protocols, we suggest several approaches on how to design cryptographic protocols that enable us to achieve our aim. Finally, we propose the design of a protocol that solves the meeting businessmen problem.

Opis:
Mobile phone may become the protagonist of the new electronic technology. If we compare it with that of other technologies, the infiltration rate of mobile phones in the world is extremely high, both in cities than rural communities of the most of the countries. According to estimates made by the International Telecommunication Union the access to mobile networks is growing much faster than the access to Internet. This emergence has led many companies to allow new activities which were previously running strictly over the Internet to run over the mobile network such as the electronic payment. These circumstances make the security of mobile communication a priority to preserve the authentication, confidentiality and integrity of data sent between subscribers and mobile network. In this paper, we propose a dynamic key generation for the A5 GSM encryption algorithm to enforce the security and protect the transferred data. Our algorithm can be implemented over any GSM generation GSM/3G/4G.
