A Fast Large-Integer Extended GCD Algorithm and Hardware Design for Verifiable Delay Functions and Modular Inversion
The extended GCD (XGCD) calculation, which computes Bézout coefficients ba, bb such that ba ∗ a0 + bb ∗ b0 = GCD(a0, b0), is a critical operation in many cryptographic applications. In particular, large-integer XGCD is computationally dominant for two applications of increasing interest: verifiable...
