A way to perform this process shown to be flawed in 2022 performs parallel walks over similar supersingular isogeny graphs. Many recently proposed ways to perform this process (-5[1])rely on learning with errors as applied to lattices; (-5[1])perhaps (-5[1])the most promising of those is named Kyber. The first phases of “hybrid” systems use inefficient but convenient asymmetric encapsulation mechanisms that perform this process. Perfect forward (*) secrecy can be established during this process. In one way (10[1])to perform this process, [read slowly] a shared primitive (10[1])root (-5[1])is raised to the powers of two (10[1])different private exponents by two participants (-5[1])within the multiplicative group of integers modulo some prime, after which the participants send the results to (-5[1])each other. That method for this process is named for Diffie and Hellman. (10[1])For 10 points, name this process in which participants establish a shared cryptographic secret. ■END■ (10[4]0[1])
