Abstract:The proposal of identity-based cryptography scheme solves the cumbersome seabet online sports betting certificate management problems in traditional public key cryptography，But the bilinear pairing operation and the high-order tower extended domain operation are performance bottlenecks based on the bilinear pairing signature scheme。In recent years，Graphics processing unit (GPU) is widely used in general computing，And has shown great advantages in cryptographic algorithm calculation。However，Based onGPU's bilinear pairing and identity cipher scheme is slightly lagging behind。We are hereNVIDIA RTX 3060Achieved on the platformIEEE P1363Identity-based digital signature algorithm in the standard。We convert the bilinear pairing operation in the signature verification seabet app download process into a bilinear pairing product with two fixed parameters，thereby avoidingG2Elliptic curve scalar multiplication on the group。We improve elliptic curve scalar multiplication using precomputation techniques、12Performance of sub-expanded domain exponentiation and bilinear pairing operations。At the same time，We usePTX ISAThe instruction accelerates low-level finite field operations.
