Toshiba Unveils Fast Formula For Elliptic-Curve Cryptography
Tokyo -- Toshiba Corp. has developed an arithmetic formula which it claims
offers the world's fastest processes of elliptic-curve cryptography. The
formula cuts processing time by almost half from current methods used in
elliptic-curve systems.
Toshiba's formula is based on the Montgomery arithmetic system, a special
method of calculation which requires no division.
Elliptic-curve cryptography is considerably faster than the Rivest Shamir
Adleman (RSA) system currently in common use.
Toshiba hopes to apply the system in a wide range of fields, including
corporate information systems and electronic commerce.
