![]() (g bmod p) amod p -Derive key- (g amod p) bmod pįor example, consider a=4 b=3 p=23 and g=5. Alice and Bob will perform the same multiplicative operation with modulo p against the values received. This exchange happens over an insecure channel. Bob calculates g bmod p and sends it to Alice. Alice chooses her private key to be a and Bob chooses b.Īlice calculates g amod p and sends it to Bob. Alice and Bob agree on two numbers g and p where p is a prime number. Let’s get into the security terms of Alice and Bob being the two entities. To understand how this is achieved, we need to understand how Diffie-Hellman key exchange and elliptical curve cryptography work in conjunction with Dragon fly key exchange.ĭiffie-Hellman Key Exchange establishes session key between two entities without actually having to exchange any key information over a public insecure channel. WPA3 replaces Pre-Shared Key with Simultaneous Authentication of Equals (SAE) to derive the Pairwise Master Key (PMK) which enables secure communication even when the password is compromised. To make it easier to understand WPA3 as a whole, I will be discussing each component individually in detail. It introduces new concepts like Simultaneous Authentication of Equals (SAE), dragonfly key exchange, NIST elliptical curve cryptography etc. It aims to alleviate the vulnerabilities in WPA2 and provide more secure wireless networks. WPA3 certification is introduced by Wi-Fi Alliance in 2018 as a successor to WPA2.
