WebMay 11, 2024 · Example: Let's say Alice picked 4 ( a=4 ), and Bob picked 3 ( b=3 ). As a next step, they will do some math on their secret numbers, they will calculate: the base ( g) in the power of their secret number, and take … WebWith Diffie-Hellman, two parties can exchange certain public values, and then combine those with private values they never shared. The result is a third value, known only to the two parties. This third value is the Diffie-Hellman Shared Secret.

The protocol is considered secure against eavesdroppers if G and g are chosen properly. In particular, the order of the group G must be large, particularly if the same group is used for large amounts of traffic. The eavesdropper has to solve the Diffie–Hellman problem to obtain g . This is currently considered difficult for groups whose order is large enough. An efficient algorithm to solve the discrete logarithm problem would make it easy to compute a or b and solve the Diffie–…
