Modular exponentiation on an 8-bit CPU (68HC11)



Hi, All
Please forgive me if this posting is in the wrong group. I'm looking
to implement the Diffie-Hellman scheme on an 8-bit 68HC11
microprocessor. Algebraically, Diffie-Hellman requires only modular
exponentiation. Can any of you point me in the right direction for
fast and efficient code for performing modular exponentiation on an
8-bit processor (HC11 in particular)?

Thanks for any help!
