In this note we study security of 128-bit key 10-round AES against the boomerang attack. We show attacks on AES reduced to 5 and 6 rounds, much faster than the exhaustive key searc...

A general method to secure cryptographic algorithm implementations against side-channel attacks is the use of randomization techniques and, in particular, masking. Roughly speaking...
