Diffie and Hellman invented a protocol where Alice and Bob share numbers in the clear and calculate the same secret number, but an eavesdropper cannot calculate the secret number except by guessing the solution to a certain mathematical problem. The Diffie-Hellman key agreement protocol depends on the mathematical problem of.
