Optimal Extension Fields for XTR
[chapter]
2003
Lecture Notes in Computer Science
Application of XTR in cryptographic protocols leads to substantial savings both in communication and computational overhead without compromising security [6] . XTR is a new method to represent elements of a subgroup of a multiplicative group of a finite field GF (p 6 ) and it can be generalized to the field GF (p 6m ) [6, 9] . This paper proposes optimal extension fields for XTR among Galois fields GF (p 6m ) which can be applied to XTR. In order to select such fields, we introduce a new notion
