"Webeavesdropping. The security of Diffie-Hellman key exchange is based on the discrete logarithm problem. Discrete logarithms Recall that a logarithm is an exponent. “2 raised to the power 5 is 32” (2 325 =)is equivalent to “the logarithm of 32 to the base 2 is 5” (2 log 32 5= ). It is relatively easy to raise numbers to powers; e.g., " - Diffie hellman example numbers
