Prior to the introduction of the Enhanced Open (EO) security method, network ecosystems that had challenges supporting Passphrase Management architecture, such as Captive-Portal systems, had to choose between either staying Open and completely unsecure, or minimally enabling WPA2-PSK, which could de-stabilize the system. With the introduction of EO based on the Opportunistic Wireless Encryption (OWE) standard, those systems can choose to use EO, which is more robust security than the WPA2-PSK, and with a better fit to the no-Passphrase-Management architecture. This mode uses OWE protocol, which is defined in the IETF document RFC 8110. OWE provides AES(CCMP128) encryption for data privacy, and PMF is required.
