  Simulation and modelling of sheet metal forming process are well common today in different industries (automotive, aerospace) and several research centers regarding its huge impact for both on production and reliability of the lifecycle of the equipment, and the quality of the product. However, to obtain the best configuration possible with the inputs parameters to achieve high level of production and increasing the durability of the tools needs some extra methods for the optimization for this problem using mostly finite element method cooperated with iterative algorithms based on Artificial Neural Network (ANN) [1]. Whereas this research is focused on modelling of stamping process of stainless steel AISI 304 to investigate to formability of the material, and studying the influence of the friction factor on the quality of the product as well the energy required for each set configuration.

  Due to the rapid growth of GNSS based techniques in everyday life a service which can provide certified location information given by GPS coordinates became a worth considering idea. We designed two protocols that can  achieve this goal, these can provide authenticate location and time information for any device which has a GPS receiver. In this article, I would like to prove -with the help of ProVerif software tool-, the latter statement. I investigated the authenticity and data integrity properties of the protocol.
