Title: Method and device for processing elliptic curve encryption
Inventor: NOGAMI YASUYUKI
IPC: G09C1/00
Filed: 2001-04-06
Abstract: PROBLEM TO BE SOLVED: To find out such finite field that multiplication can be quickly executed with a normal basis for the purpose of quick processing of elliptic curve encryption. SOLUTION: An extension Galois field GF (PP) where the same prime P is taken as a characteristic P, and an extension degree m is used in a extension GF (P<m> ) to realize quick processing. It is proved that a conjugate set of ω, which gives f(ω)=0 is included in the normal basis in the extension GF (PP), with respect to an irreducible polynomial of degree P, given by f(x)=xP-xP<-1> +1 on the GF (P). Quick multiplication with the normal basis and self dual basis representation is made possible. For example, a GF (31<31> ) and GF (61<61> ) can be used. In the case of the GF (31<31> ), the key length corresponds to 160 bits and results in 31<31> ≈2<155> , and the number of times of multiplication is (5m<2> -m)/2 and is smaller than the conventional by (m<3> -3m)/2 number of times tough the key length is approximately equal to that for a conventional GF (2<160> ).
