This paper proposes a compact and efficient GF (2) inversion circuit design based on a combination of non-redundant and redundant Galois Field (GF) arithmetic. The proposed design utilizes redundant GF representations, called Polynomial Ring Representation (PRR) and Redundantly Represented Basis (RRB), to implement GF (2) inversion using a tower field GF(More)
This paper introduces pairing-based cryptography focusing on homomorphic cryptography. Pairing is a bilinear map from two rational point groups to a multiplicative group in extension field. The bilinearity is used for realizing recent innovative cryptographies. In these years, it is applied to some homomorphic encryptions though it needs a heavy(More)
