Differential Power Analysis Attack on FPGA Implementation of AES
Cryptographic devices have found their way into a wide range of application and the topic of their security has reached great research importance. It has been proved that encryption device leaks information, which can be exploited by various attacks such as power analysis, timing analysis and electro-magnetic radiation. Differential power analysis is a powerful and efficient cryptanalytic techn...
متن کاملImproved Collision-Correlation Power Analysis on First Order Protected AES
The recent results presented by Moradi et al. on AES at CHES 2010 and Witteman et al. on square-and-multiply always RSA exponentiation at CT-RSA 2011 have shown that collision-correlation power analysis is able to recover the secret keys on embedded implementations. However, we noticed that the attack published last year by Moradi et al. is not efficient on correctly first-order protected imple...
متن کاملA Comprehensive FPGA-Based Assessment on Fault-Resistant AES against Correlation Power Analysis Attack
The secret key used in a cryptosystem can be retrieved by physical attacks such as side-channel analysis (SCA) and fault analysis (FA) attacks. Traditionally, countermeasures for different physical attacks are developed in a separate fashion. To lay a solid foundation for countermeasure development for the emerging combined attacks, it is imperative to thoroughly study how the countermeasure fo...
متن کاملCorrelation-Enhanced Power Analysis Collision Attack
Side-channel based collision attacks are a mostly disregarded alternative to DPA for analyzing unprotected implementations. The advent of strong countermeasures, such as masking, has made further research in collision attacks seemingly in vain. In this work, we show that the principles of collision attacks can be adapted to efficiently break some masked hardware implementation of the AES which ...
متن کاملEnhanced Flush+Reload Attack on AES
In cloud computing, multiple users can share the same physical machine that can potentially leak secret information, in particular when the memory de-duplication is enabled. Flush+Reload attack is a cache-based attack that makes use of resource sharing. T-table implementation of AES is commonly used in the crypto libraries like OpenSSL. Several Flush+Reload attacks on T-table implementat...
