Title:
Techniques for random maskin in hardware
Authors: Jovan Dj. Golic
Abstract:A new technique for Boolean random masking of the logic AND operation in terms of NAND logic gates
is presented and its potential for masking arbitrary cryptographic functions is pointed out.
The new technique is much more efficient than a previously known technique, recently applied to AES.
It is also applied for masking the integer addition.
In addition, new techniques for the conversions from Boolean to arithmetic random masking and vice versa
are developed. They are hardware oriented and do not require additional random bits.
Unlike the previous, software-oriented techniques showing a substantial difference in the complexity
of the two conversions, they have a comparable complexity being about the same as that
of one integer addition only.
All the techniques proposed are in theory secure against the first-order differential
power analysis on the logic gate level.
They can be applied in hardware implementations of various cryptographic functions,
including AES, (keyed) SHA-1, IDEA, and RC6.
