  • Method for efficient computation of odd characteristic extension fields
    Patent number: 7069287
    Abstract: A method for implementing an elliptic curve or discrete logarithm cryptosystem on inexpensive microprocessors is disclosed which provides for advantageous finite field computational performance on microprocessors having limited computational capabilities. The method can be employed with a variety of commercial and industrial imbedded microprocessor applications such as consumer smart cards, smart cards, wireless devices, personal digital assistants, and microprocessor controlled equipment. In one embodiment, a Galois Field (GF) implementation based on the finite field GF((28?17)17) is disclosed for an Intel 8051 microcontroller, a popular commercial smart card microprocessor. The method is particularly suited for low end 8-bit and 16-bit processors either with or without a coprocessor.
