Latest Patents
One of Pil-joong Lee's key patents is titled "Method for exponentiation in a public-key cryptosystem." This invention relates to an improved method for performing modular exponentiation to a fixed base element. The method involves exponentiating a first digital input signal g by a second digital input signal R, where g is a fixed signal unique to a cryptographic system and R is a randomly generated digital signal. This process computes a third digital signal g.sup.R. The method includes pre-computing and storing a plurality of values based solely on the fixed signal g in various memory locations within a computing device. This approach significantly speeds up the computation of g.sup.R by utilizing the stored values. The exponentiation method can substantially reduce the computational load required to compute the value for g.sup.R. Furthermore, this method can be applied in various cryptographic systems, including the Schnorr identification scheme, Digital Signature Standard (DSS), and Diffie-Hellman key agreement scheme.
