![]() SPEKE stands for Simple Password Exponential Key Exchange. The Dragonfly handshake is essentially a SPEKE protocol. In fact both parties prove that they have knowledge over the same password.Ĭryptographic overview of Dragonfly and SPEKE WPA3 makes use of such a zero knowledge proof to ensure that no secrets of the passwords are transmitted in the SAE handshake, but both handshake participants can be sure that the other party knows that they possess the same and correct password. Use the new dragonfly handshake such that they can use the label WPA3.Ī zero knowledge proof is a cartographic protocol that enables one party to to prove to another party that they know a value x without conveying any information other than the fact that they know the value of x. It's up to the vendors to decide which of those three voluntary features they are going to implement in their products. However with WPA, PMF are included from the start in the certification program. WPA2 already supports this, therefore this is not a novelty of WPA3. Only mandatory when certified as WPA3-EnterpriseĪdditionally, WPA3 supports Protected Management Frames (PMF) which makes it impossible to launch de-authentication attacks. Increased key sizes with 192-bit sized keys.Protective mechanisms in open networks based on unauthenticated encryption.Refereed to as Wi-Fi CERTIFIED Easy Connect program. A straightforward method to securely add devices to a network.A new handshake called dragonfly (also called Simultaneous Authentication of Equals) that is resistant against dictionary attacks and provides forward secrecy.Only one is mandatory: The new dragonfly handshake. WPA3 is a certification program and it supports four major features of which The presentation slides can be downloaded here: What is new in WPA3Īs the name suggest, WPA3 is the successor of WPA2. 10.4 802.11 candidate frames for fuzzingĪ implementation of the rfc7664 dragonfly key exchange using ECC can be found here:.10.3 Use monitor or master mode for fuzzing?.10.2 Which parts of the Dragonfly handshake might be candidates for vulnerable implementations?.10.1 Reasons that make fuzzing promising.7 Offline dictionary attack against WPA2 handshake.5.2 Establishing a Pairwise Master Key in SAE with ECC.5.1 Simultaneous Authentication of Equals (SAE).5 Dragonfly handshake (Simultaneous Authentication of Equals).4 Cryptographic overview of Dragonfly and SPEKE. ![]()
