Finite field multiplier is a very important operation for realising elliptic curve cryptography. Dickson basis is a recently developed basis for representing finite elements in GF(2 m ). This study will propose a unidirectional systolic multiplier for such Dickson basis. The unidirectional systolic structure offers low space and time complexities and can be easily modified to have error detection capability which can resist side‐channel attacks.
