Nowadays, use of wireless networks and devices is inevitable due to their beneficial features, such as ease of use, portability, rapid and comfortable access to information. On the other hand, the security for wireless networks is a challenging matter by overwhelming increase over the number of mobile hardware and devices. Mobile Ad-hoc network (MANET) is a class of wireless networks, which forms dynamically by joining or leaving the nodes into/from the network without any fix infrastructure. This kind of network in comparison to other types of networks, is prone to various security threats or attacks due to its unique characteristics (dynamic topology, open medium, lack of central... 

Using cryptographic hardware device is inevitable these days. Hence, the secret information inside these devices should be safe and non-attackable. Simple and differential Power analysis (SPA, DPA), a form of side channel attack, allows attacker to study circuit information leakage by analyzing and monitoring power consumption of a cryptographic hardware device to extract inside information and discovering the secret keys. In this thesis, first, a sample cryptographic hardware device is designed and implemented as an under attack system. Then, another device is designed as an attacker in order to attack the mention sample hardware by analyzing and monitoring its power consumption. A digital...
