Mutual authentication or two-way authentication is a process in which two entities in communication authenticates each other before any application data is transferred. This is typically achieved by exchange of digital certificates issued by trusted entities. Mutual authentication helps in eliminating the man-in-the-middle attack, where an adversary establishes independent links with both the victims and relays messages between them. The victims are led to believe that they are in direct communication, while infact, the entire communication between them is controlled by the adversary.
