Side-channel attacks are now-a-days a serious concern when implementing cryptographic algorithms. Powerful ways for gaining information about the secret key as well as various countermeasures against such attacks have been recently developed. Although it is well known that such attacks can exploit information leaked from different sources, most prior works have only addressed the problem of protecting a cryptographic device against a single type of attack. Consequently, there is very little knowledge on how a scheme for protecting a device against one type of side-channel attack may affect its vulnerability to other types of side-channel attacks.
