Research on the DES Physical Observable Security
Qiang Zhao · Dianzi xuebao · 2009
The security of cryptographic implementations with respect to observation named side-channel attacks,in which adversaries are enhanced with the possibility to exploit physical leakages such as power consumption or electromagnetic radiation.A lot of countermeasures have been experimented,but do not fundamentally prevent them.In this paper,DES is implemented on AT89C52.DPA and countermeasure experiments have been done on this platform.Physically Observable cryptography is built by Micali and Reyzin who initiated a theoretical analysis of side-channels.Our work is to apply the Physical-Observation attacks to practice for Symmetric Encryption schemes and find out how it is applied to DES-DPA attack practice for Symmetric Encryption schemes with random oracle model.
