Abstract

The invention discloses a novel pulse node type scalar point multiplication double-domain implementation system and method, which adopts a semi-autonomous learning design combining random dynamic table establishment and coordinate mapping derivation formula calculation, combines and uses pulse node values and high-frequency node values in the random table establishment, and adopts the advantage of integration of storage and calculation in the derivation formula, so as to realize the double-domain implementation of the pulse node type scalar point multiplication. The node calculation value position is the position in the random table, so that the cross calling of the formula mapping calculation value and the point value data in the random table is realized, finally, the efficient operation of the pulsation node with the memory of the scalar point multiplication data is realized, and the overall implementation efficiency of the scalar point multiplication is improved; the method is mainly applied to the function implementation of the cryptographic service of the asymmetric cryptography based on the elliptic curve, and the scalar point multiplication operation on the Fp domain and the scalar point multiplication operation on the Fp2 domain are emphatically realized, so that the application of encryption and decryption and signature verification of SM2 and SM9 algorithms is supported.

Description
