Enhanced 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...

متن کاملDifferential Power Analysis: A Serious Threat to FPGA Security
Differential Power Analysis (DPA) implies measuring the supply current of a cipher-circuit in an attempt to uncover part of a cipher key. Cryptographic security gets compromised if the current waveforms obtained correlate with those from a hypothetical power model of the circuit. As FPGAs are becoming integral parts of embedded systems and increasingly popular for cryptographic applications and...
متن کاملHardware Implementation of Dynamic S-BOX to Use in AES Cryptosystem
One of the major cipher symmetric algorithms is AES. Its main feature is to use S-BOX step, which is the only non-linear part of this standard possessing fixed structure. During the previous studies, it was shown that AES standard security was increased by changing the design concepts of S-BOX and production of dynamic S-BOX. In this paper, a change of AES standard security is studied by produc...
متن کاملAn Analysis of XSL Applied to BES
Currently, the only plausible attack on the Advanced Encryption System (AES) is the XSL attack over F256 through the Big Encryption System (BES) embedding. In this paper, we give an analysis of the XSL attack when applied to BES and conclude that the complexity estimate is too optimistic. For example, the complexity of XSL on BES-128 should be at least 2 instead of the value of 2 from current l...
