<span>Nowadays, with the advences in ICT and rapid development of mobile internet; media information shared on the various communication networks requires the existence of adequate security measures. Cryptography becoming an effective way to meet these requirements and for maintain the confidentiality. However, communicating with encrypted messages requires secret key exchange, which is a part of a complex protocol. In this paper, we propose a new method for exchanging key based on Diffie-Hellman protocol and image registration with fast fourier transform, the principle of this method consists to concealing the key in a set of transformed images. Therefore, image registration allows finding transformations between images, which become a tool for recovering the key by the receiver.</span>

Vehicular Communication Networks

In a former paper [Fluct. Noise Lett. 13 (2014) 1450020] we introduced a vehicular communication system with unconditionally secure key exchange based on the Kirchhoff-Law–Johnson-Noise (KLJN) key distribution scheme. In this paper, we address the secure KLJN key donation to vehicles. This KLJN key donation solution is performed lane-by-lane by using roadside key provider equipment embedded in the pavement. A method to compute the lifetime of the KLJN key is also given. This key lifetime depends on the car density and gives an upper limit of the lifetime of the KLJN key for vehicular communication networks.

The Village

Bumdes is a village business unit whose capital comes from village-owned funds . The goal is to float the village potential into an independent village. Thus it takes effort and strategic and appropriate tips to achieve that goal. The first tip is to establish a forum for the development of economic networks in this case is the establishment of BUMDES. Some of the things that can be done are: (i) development of human resources capability so as to provide added value in the management of village economic assets, (ii) integrating rural economic products so as to have good bargaining position in market network, (iii) (iv) strengthening village economic institutions, (v) developing supporting elements such as micro-credit, market information, technological and management support, economic infrastructure and communication networks as well as support for guidance and regulation.
