- Abstract:
- 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 oscilloscope with high frequency sample rate is used in order to obtain the real data. The result is compared with original data and the power consumption analysis problems were identified and reduced through the introduction of a suitable model of analysis to have a successful attack. Finally some solutions were suggested for preventing attacks on complex systems
