Slicing Up a Perfect Hardware Masking Scheme
—Masking is a side-channel countermeasure that randomizes side-channel leakage, such as the power dissipation of a circuit. Masking is only effective on the condition that the in...

Lower Bounds on Signatures From Symmetric Primitives
We show that every construction of one-time signature schemes from a random oracle achieves black-box security at most 2(1+o(1))q , where q is the total number of oracle queries a...
