Abstract
A scalar multiplication can be performed on an elliptic curve cryptosystem at a high speed. P is set as an initial value of Q[], and 2×P is set as an initial value of Q[. An elliptic curve doubling ECDBL of Q[d[i]] is performed, and an arithmetic result is stored in Q[. An elliptic curve addition ECADD of Q[and Q[is performed, and an arithmetic result is stored in Q[. Q[d[i]] is stored in Q[. Q[+d[i]] is stored in Q[. The elliptic curve addition ECADD and the elliptic curve doubling ECDBL are concurrently performed in the respective processors.
