| 20090074178 | Accelerating Scalar Multiplication On Elliptic Curve Cryptosystems Over Prime Fields - A method and apparatus for accelerating scalar multiplication in an elliptic curve cryptosystem (ECC) over prime fields is provided. Multiplication operations within an ECC point operation are identified and modified utilizing an equivalent point representation that inserts multiples of two. Algebraic substitutions of the multiplication operations with squaring operations and other cheaper field operations are performed. Scalar multiplication can also be protected against simple side-channel attacks balancing the number of multiplication operations and squaring operations and providing novel atomic structures to implement the ECC operation. In addition, a new coordinate system is defined to enable more effective operation of ECC to multiprocessor environments. | 03-19-2009 |
| 20090323933 | Exponentiation method using multibase number representation - A method of scalar multiplication for use in elliptic curve-based cryptosystems (ECC) is provided. Scalars are represented using a generic multibase form combined with the non-adjacency property, which greatly reduces the nonzero density in the representation. The method allows for flexibly selecting an unrestricted number of bases and their weight in the representation according to the particular characteristics of a setting, in such a way that computing costs are minimized. A simple, memory-friendly conversion process from binary to multibase representation and an inexpensive methodology to protect the multibase scalar multiplication against simple-side channel attacks are also provided. | 12-31-2009 |
